About this network

A university /16, and one address still answering with a dialup pool name.

What it's used for

• A university network. Two IPv4 prefixes announced from the United States, no IPv6, and two observed BGP neighbours.

Notable

• The larger block is a /16, sixty-five thousand addresses issued when universities were given space on that scale.
• The smaller block is registered to a carrier under the netname CENTURYLINK-LEGACY-QWEST-INET-32, which names the current carrier, the word legacy, the acquired carrier, a service type and a counter in one label.
• Its one answering address is p64.Greeley.dialup.csn.net: a port number, a city with a capital letter, the word dialup, and a fourth domain belonging to none of the parties on record.
• The university's registrant field appends a domain name administrator role after a semicolon.
• Six addresses were queried for reverse DNS and one returned a name.

Interesting

• That reverse name is a fossil. It describes a modem port on a service that has not been sold for a generation, and it still resolves because nobody has had a reason to remove the zone.
• A netname that carries the word legacy is a carrier admitting its own history in a field meant for identification. It survives every rebrand because changing it means touching every record.
• Sixty-five thousand addresses for one institution is an allocation from an era of abundance. No university applying today would be given anything close.
