AS12243 — WADDELL

AS12243 announces 7 IPv4 prefixes covering 2,048 addresses and 2 IPv6 prefixes.

About this network

A small provider announcing more IPv6 prefixes than it has IPv4 addresses to spare.

What it's used for

• Provider and hosting connectivity. 2,048 addresses in seven IPv4 prefixes, eighteen IPv6 prefixes, and eleven observed BGP neighbours.

Notable

• Three of the seven IPv4 blocks are netname COGENT-A, registered to Cogent Communications rather than to the announcing company.
• The company's own netnames say what the space is for: WSG-PROVIDER-BLK1, WSG-ISP-64 and WSG-46.
• The IPv6 side is 2606:1040::/36 announced together with a staircase of children — a /48, another /48, then /47, /46, /45, /44, /43, /42, /41 and on.

Interesting

• Seven IPv4 prefixes averaging under 300 addresses each is what building a network after exhaustion looks like. Nobody is allocated a contiguous block any more; you take a /24 here, a /24 from your transit provider there, and the routing table records every one of them.
• The IPv6 announcements outnumber the IPv4 ones more than two to one. There is no shortage driving that, so it is structure showing through — each doubling step is a boundary somebody drew inside the network and then advertised outward.
