Abstract
Three IPv4 unicast address blocks are reserved for use in examples in
Arkko, et al. Expires December 14, 2009 [Page 1]
Internet-Draft IPv4 Examples June 2009
specifications and other documents. This document describes the use
of these blocks.
1. Introduction
This document describes the IPv4 address blocks that are provided for
use in documentation. The use of designated address ranges for
documentation and examples reduces the likelihood of conflicts and
confusion arising from the use of addresses assigned for some other
purpose.
[RFC1166] reserves the first of the three address blocks,
192.0.2.0/24. The other two address blocks have recently been
allocated for this purpose, to ease the writing of examples involving
addresses from multiple networks.
These addresses are complementary to other documentation ranges
defined in the IETF, including the IPv6 documentation prefixes
[RFC3849] and example domain names [RFC2606].
2. 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 BCP 14, [RFC2119].
3. Documentation Address Blocks
The blocks 192.0.2.0/24 (TEST-NET-1), 198.51.100.0/24 (TEST-NET-2),
and 203.0.113.0/24 (TEST-NET-3) are provided for use in
documentation.
4. Operational Implications
Addresses within the TEST-NET-1, TEST-NET-2, and TEST-NET-3 blocks
SHOULD NOT appear on the public Internet and are used without any
coordination with IANA or an Internet registry [RFC2050]. Network
operators SHOULD add these address blocks to the list of non-
routeable address space, and if packet filters are deployed, then
this address block SHOULD be added to packet filters.
These blocks are not for local use, and the filters may be used in
both local and public contexts.

5. Security Considerations
This document has no security implications.
6. IANA Considerations
IANA should record the allocation of the three address blocks in the
IPv4 address registry. No end party is to be assigned these
addresses.
