Internet-Draft iris-areg August 2004
1. Introduction
This document describes an IRIS namespace for Internet address
registries using an XML Schema [5] derived from and using the IRIS
[9] schema. This schema and registry type are provided to
demonstrate the extensibility of the IRIS framework beyond the use of
domains, a criteria defined in CRISP [11].
The schema given is this document is specified using the Extensible
Markup Language (XML) 1.0 as described in XML [2], XML Schema
notation as described in XML_SD [4] and XML_SS [5], and XML
Namespaces as described in XML_NS [3].
Examples of client/server XML exchanges with this registry type are
available in Appendix A.

2. Document Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC2119 [8].

3. Schema Description
IRIS requires the derivation of both query and result elements by a
registry schema. These descriptions follow.
The descriptions contained within this section refer to XML elements
and attributes and their relation to the exchange of data within the
protocol. These descriptions also contain specifications outside the
scope of the formal XML syntax. Therefore, this section will use
terms defined by RFC 2119 [8] to describe the specification outside
the scope of the formal XML syntax. While reading this section,
please reference Section 5 for needed details on the formal XML
syntax.
3.1 Query Derivatives
3.1.1 <findContacts> Query
<findContacts> searches for contacts given search constraints.
The child element <commonName> allows the search to be constrained
against the name of the contact. This element may have as a child
the <exactMatch> element.
<eMail> constrains the query based on the e-mail address of the
contact. This may be done by an exact e-mail address using the
<exactMatch> element or by any e-mail address in a domain using the
<inDomain> element. The <inDomain> element MUST only contain a valid
domain according to RFC 1035 [1] (i.e. no '@' symbol).
<findContacts> queries MUST be case insensitive.
3.1.2 <findOrganizations>
The <findOrganizations> element allows searches by name of
organisations.
The child element <name> may have as child the <exactMatch> element.
3.1.3 <findAutonomousSystems> and <findNetworks>
The <findAutonomousSystems> and <findNetworks> elements allow
searches by handle of autonomous systems, and networks, respectively.
Both have the same format.
The child element <specificity> - determines the ASN range
specificity for the search (see Section 4). Valid values are
"all-less-specifics", "one-level-less-specifics",
Gunduz & Newton Expires February 3, 2005 [Page 5]
Internet-Draft iris-areg August 2004
"all-more-specifics", "one-level-more-specifics" and "closes-match".
This element may have the optional attribute 'allowEquivalences'.
When set to "true", the result set should include ASN ranges with
equivalent starting and ending ASNs.
3.1.4 <findNetworkByAddress>
The <findNetworkByAddress> element is a query for a network given a
related IP address, IP address range, or network handle. It has the
following child elements:
o <ipv4Address> - has a child <start> element containing the
starting IPv4 address of the network and an optional child of
<end> containing the ending IPv4 address of the network.
o <ipv6Address> - same as <ipv4Address> but the child addresses
contain IPv6 addresses. Clients MUST convert any short-form
notation to the fully-qualified notation.
o <specificity> - determines the network specificity for the search
(see Section 4). Valid values are "all-less-specifics",
"one-level-less-specifics", "all-more-specifics",
"one-level-more-specifics" and "closest-match". This element may
have the optional attribute 'allowEquivalences'. When set to
"true", the result set should include networks with equivalent
starting and ending addresses.
The results from this query MUST be either the <ipv4Network> result
or the <ipv6Network> result. More than one network result MAY be
returned.
3.2 Result Derivatives
3.2.1 <ipv4Network> and <ipv6Network> Results
The <ipv4Network> and <ipv6Network> share a common defintion of
'ipNetworkType'. It has the following child elements:
o <networkHandle> contains the registry-unique assigned handle for
this network.
o <startAddress> contains the first IP address of the network.
o <endAddress> contains the last IP address of the network.
o <networkType> contains a string denoting the type of network.
* <networkTypeInfoURI> contains a URI where the meanings of the
values are explained in a plain natural language.
o One or more <nameServer> elements, each containing the domain name
of a nameserver responsible for reverse-DNS mapping for this
network.
o <organization> contains an entity reference to the organization
assigned this network. The referent MUST be an <organization>
(Section 3.2.4) result.
Gunduz & Newton Expires February 3, 2005 [Page 6]
Internet-Draft iris-areg August 2004
o One of:
* <parent> contains an entity reference to the parent network of
this network. The referent MUST be an <ipv4Network> (Section
3.2.1) result if this reference is a child of <ipv4Network>.
The referent MUST be an <ipv6Network> (Section 3.2.1) result if
this reference is a child of <ipv6Network>.
* <noParent> contains no children and simply signifies that the
network does not have a parent.
o Contact references (see Section 3.2.5).
o Common child elements (see Section 3.2.6).
3.2.2 <autonomousSystem> Result
The <autonomousSystem> element represents an assigned autonomous
system. It has the following children:
o <asHandle> contains a registry-unique assigned handle for this
autonomous system.
o <asNumberStart> contains an integer indicating the starting number
for the autonomous system.
o <asNumberEnd> contains an integer indicating the ending number for
the autonomous system.
o <organization> contains an entity reference to the organization
assigned this autonomous system. The referent MUST be an
<organization> (Section 3.2.4) result.
o One of:
* <parent> contains an entity reference to the parent ASN range
of this ASN range. The referent MUST be an <autonomousSystem>
(Section 3.2.2) result.
* <noParent> contains no children and simply signifies that the
network does not have a parent.
o Contact references (see Section 3.2.5).
o Common child elements (see Section 3.2.6).
3.2.3 <contact> Result
The <contact> element represents the registration of a point of
contact. It has the following child elements:
o <contactHandle> contains the registry-unique assigned handle for
this contact.
o Either <firstName>, <middleName>, and <lastName> or <role>. The
first three elements specify the name of the contact broken down
into the common components of a persons name. The latter element,
<role>, specifies that the contact is a group of people given the
responsibility described by this element.
o <eMail> contains the email address for this contact.
o <sip> contains the sip address for this contact.
o <organization> contains an entity reference to the organization
associated with this contact. The referent MUST be an
Gunduz & Newton Expires February 3, 2005 [Page 7]
Internet-Draft iris-areg August 2004
<organization> (Section 3.2.4) result.
o <phone> contains child elements describing the phone number of the
contact. The child elements are <number>, <extension>, and
<type>.
o Common child elements (see Section 3.2.6).
3.2.4 <organization> Result
The <organization> element represents an organization. It has the
following child elements:
o <name> contains the name of the organization.
o <id> contains a registry-unique identifier for this organization.
o <address> contains the address for this organization.
o <city> contains the city where this organization is located.
o <region> contains the national region where this organization is
located.
o <postalCode> contains the postal code where this organization is
located.
o <country> contains the country code where this organization is
located. This MUST be compliant with ISO 3166 [12] two-character
country codes.
o Contact references (see Section 3.2.5).
o Common child elements (see Section 3.2.6).
3.2.5 Contact References
The registry schema defined in Section 5 normalizes out a group of
elements used to reference contacts. This group is used by many of
the result types for this registry. The group has the following
elements, each of which may appear as many times as needed. The
referent of each MUST be <contact> (Section 3.2.3) results.
o <adminContact>
o <techContact>
o <nocContact>
o <abuseContact>
o <otherContact>
3.2.6 Common Result Child Elements
The registry schema defined in Section 5 normalizes out a group of
common elements used most of the reult types. The group has the
following elements:
o <numberResourceRegistry> contains an entity reference to the
number resource registry of record. The referent MUST be an
<organization> (Section 3.2.4) result.
o <registrationDate> contains the date of first registration.
o <lastUpdatedDate> contains the date when the registration was last
updated.
Gunduz & Newton Expires February 3, 2005 [Page 8]
Internet-Draft iris-areg August 2004
o The <iris:seeAlso> element contains an entity reference specifying
an entity that is indirectly associated with this result object.
3.3 Support for <iris:lookupEntity>
The following types of entity classes are recognized by the
<lookupEntity> query of IRIS for this registry:
o ipv4-handle - a registry unique identifier specifying an IPv4
network. Queries with these names will yield a <ipv4Network>
result.
o ipv6-handle - a registry unique identifier specifying an IPv6
network. Queries with these names will yield a <ipv6Network>
result.
o autonomous-system - the positive integer (ASN) specifying an
autonomous system. It yields a result of <autonomousSystem>.
o as-handle - a registry unique identifier specifying an autonomous
system. It yields a result of <autonomousSystem>.
o contact-handle - a registry unique identifier of a contact.
Yields a result of <contact>.
o organization-id - a registry unique identifier of an organization.
Yields a result of <organization>.
o The entity names of these entity classes are case insensitive.

4. Terminology for Nesting of Networks
The following terms are defined for describing the nesting of IP
networks.
o More specific: Given two networks, A and B, A is more specific
than B if network B includes all space of network A, and if
network B is larger than network A.
o Less specific: Opposite of more specific. The network B is less
specific than network A if network A's all space is included in
network B and if network A is smaller than network B.
o Most specific: Given a set of networks, the network or networks
that are more specific than zero or more of other networks in the
set, and that are not a less specific of any of the networks in
the set.
o Least specific: Given a set of networks, the network or networks
that are not more specific to any of the other networks in the
set.
Examples:
+-------------------------------------------------------+
| |
| Given the networks A, B, C and D as follows: |
| |
| A |---------------------------------| |
| B |-----------------| |
| C |---------| |
| D |-------| |
| |
| |
| The network A is less specific than B, C and D. |
| The network B is more specific than A. |
| Among these four networks, A is the least specific, |
| and C and D are the most specific networks. |
| |
+-------------------------------------------------------+
Figure 1: Nesting Example 1
Gunduz & Newton Expires February 3, 2005 [Page 10]
Internet-Draft iris-areg August 2004
+-------------------------------------------------------+
| |
| Given the networks E, F and G: |
| |
| E |----------| |
| F |--------------| |
| G |---| |
| |
| The networks E and F are least specific networks. |
| The networks F and G are most specific networks. |
| |
+-------------------------------------------------------+
Figure 2: Nesting Example 2
The following definitions assume that there are no overlapping
networks in the database. A network overlaps with another one when
they encompass each other's space partially. Examples:
A |---------------------|
B |----------------------------|
Figure 3: Nesting Example 3
C |------------------|
D |---------|
Figure 4: Nesting Example 4
Here, the networks C and D are NOT overlapping networks, because even
if network D encompasses a part of network C's space, network C does
not encompass network D's space partially (it encompasses network D
completely).
The address directory can contain more than one network with the same
range. They are said to be exact match networks.
Parent/child relationship in the internet address directory is
unidirectional. That is, there might also be parent/child
relationship with exact match networks, but a network cannot be a
parent and a child of its exact match network at the same time.
Nested matching searches:
[1] Given a range, find all the networks that contain that range (ie,
all less specifics and exact matches). These networks are the
networks that fulfill the following condition:
Gunduz & Newton Expires February 3, 2005 [Page 11]
Internet-Draft iris-areg August 2004
(start(network) <= start(search)) AND (end(network) >= end(search))
[2] Given a range, find only the most specific network that contains
that range (could be multiple networks, but usually single); This is
the set of networks from [1], with the provision that: no network in
the return set is contained by any other network in the set. If
there are exact match networks in the set from [1], they both must
appear in the result set. The result set must not contain a network
that is exact match to the query range.
A |-------------------------------|
B |---------------------------|
C |-------|
Query |- - - - - - - - - -|
Figure 5: Nesting Example 5
In the above case, the query must return B.
A |-------------------------------|
B |---------------------------|
C |---------------------------|
D |-------|
Query |- - - - - - - - - -|
Figure 6: Nesting Example 6
Here, the query must return B and C (they are exact matches of each
other).
A |-------------------------------|
B |---------------------------|
C |---------------------------|
D |-------|
Query |- - - -|
Figure 7: Nesting Example 7
Here, the query must return B and C (they are exact matches of each
other). D must not be in the result set, as it is exact match to the
query.
[3] Given a range, find all the networks that are fully within that
range. The set must not contain an exact match:
(start(network) >= start(search)) AND (end(network) <= end(search))
Gunduz & Newton Expires February 3, 2005 [Page 12]
Internet-Draft iris-areg August 2004
AND NOT ((start(network) = start(search)) AND (end(network) =
end(search)))
[4] Given a range, find only the least specific networks that are
fully within that range. This is the set of networks from [3], with
the provision that:
no network in the return set contains any other network in the return
set.
Query |- - - - - - - - - - - - - - - - - - - - - - -|
A |------------------|
B |-------------------------|
C |--------|
D |---------|
Figure 8: Nesting Example 8
[5] Given a range, find the networks that begin and end on the same
IP addresses as the range ("exact match").
That is, the networks that fulfill the following condition:
(start(network) = start(search)) AND (end(network) = end(search))
[6] Given a range find the exact match network if exists, and if not,
perform the [2] search.
For the cases [1]-[6], if a network handle is given as the input,
then the server must find the network with this handle, and then
perform the specified search for its range.
Parent-child relationship searches:
[7] Given a network handle, find the network that is the direct (one
level up) parent of the network with the given handle.
[8] Given a network handle, find the network or networks that are
direct (one level down) children of the network with the handle
given.

6. BEEP Transport Compliance
IRIS allows several extensions of the core capabilities. This
section outlines those extensions allowable by IRIS-BEEP [10].
6.1 Message Pattern
This registry type uses the default message pattern as described in
IRIS-BEEP [10].
6.2 Server Authentication
This registry type uses the default server authentication method as
described in IRIS-BEEP [10].

Internet-Draft iris-areg August 2004
7. URI Resolution
7.1 Application Service Label
The application service label associated with this registry type MUST
be "AREG1". This is the abbreviated form the URN for this registry
type, urn:ietf:params:xml:ns:areg1.
7.2 Top-Down Resolution
The top-down alternative resolution method MUST be identified as
'top' in IRIS URI's.
The process for this resolution method differs from the
direct-resolution method if the authority is only an IP address (i.e.
without the port number). The process for this condition is as
follows:
1. The IP address is converted into a domain name appropriate for
the reverse DNS tree mapping. For instance, 64.83.37.226 is
226.37.83.64.in-addr.arpa.
2. The reverse-map domain name is reduced to the appropriate least
two components (e.g. "in-addr.arpa").
3. The IRIS [9] direct resolution method is tried on this
reverse-map domain name.
4. If no records are found, then the component in the original
reverse-map domain name to the right of the left-most component
of this reverse-map domain name is prepended, and the third step
is repeated (e.g. if "in-addr.arpa" then "64.in-addr.arpa", if
"64.in-addr.arpa" then "83.64.in-addr.arpa").
5. If all the components of the original reverse-map domain name
from step one are present and no records are found, then the
original IP address is used and the port number used is the
well-known port for the default protocol of IRIS.

8. Internationalization Considerations
This document lays out no new considerations for internationalization
beyond that specified in IRIS [9].

9. IANA Considerations
The following URN will need to be registered with IANA according to
the IANA considerations defined in IRIS [9]:
urn:ietf:params:xml:ns:areg1
The following NAPSTR application service label will need to be
registered with IANA according to the IANA considerations defined in
IRIS [9]:

Appendix B. Acknowledgements
Many of the concepts concerning the use of SRV records for step-wise
refinement towards finding authoritative servers and many of the
details of result objects in this draft were originally created by
Eric A. Hall in his memos regarding the use of LDAP to satisfy the
CRISP requirements. These concepts have contributed significantly to
the development of this protocol.
