Internet2 Prefix-Length Policy

The following was sent to the Internet2 operations list on 17 January 2003.


Internet2 encourages its connectors to aggregate advertised prefixes as an internet best practice. Therefore, we will accept approved IPv4 prefixes up through /27. However, we realize that in unusual special cases, prefixes more specific than /27 must be advertised, so if there is an important reason a prefix more specific than /27 must be advertised, explain your need and we will try to accomodate you.

Since connectors are the only ones from whom specific prefixes are accepted, this policy applies so far only to Internet2 connectors (i.e. not to peer networks).

Your request has been completed.
