AS13937 announces 1 IPv4 prefixes covering 512 addresses and 1 IPv6 prefixes.

About this network

The netname says anycast and the routing shows one neighbour, which is anycast with nowhere to cast to.

What it's used for

• A Canadian access provider. 512 addresses in a single IPv4 prefix, one IPv6 prefix, and one observed BGP neighbour.

Notable

• The block is 204.239.130.0/23, netname UNISERVE-ANYCAST, registered to Okanagan Internet Junction.
• The AS handle is UNISERVE-AS13937, the company name followed by its own AS number.
• The IPv6 prefix is 2605:1000:a::/47.

Interesting

• Announcing the same addresses from several places is what anycast means, and it needs several places to announce from. One upstream gives one path, so the netname records an intention, a past arrangement, or a plan that the routing table has yet to catch up with.
• The registrant is a different company from the one the AS is named for, which is the ordinary aftermath of a regional provider absorbing a smaller one. The addresses keep the older name because changing a registry record achieves nothing operationally.
• Putting the AS number in the handle is redundant and useful. The handle already identifies the network, but a human reading a routing table sees the same string twice and needs no second lookup to confirm it.
