Sample XML registry for IPv4 address space

IANA is currently engaged in a project to convert the protocol registries IANA maintains to XML to provide the community with improved ways of viewing registry information. An example of the registry with XML as the source has been published as a demonstration to the community.

You should not encode this URL in any enduring location, such as in computer software.
