AS12131 — VC-AS-02

AS12131 announces 2 IPv4 prefixes covering 768 addresses and 2 IPv6 prefixes.

About this network

A small network with 14 neighbours, two IPv6 /32s, and a /23 the registry still lists as its own.

What it's used for

• Hosting and connectivity. 768 addresses in two IPv4 prefixes, two IPv6 /32s, and 14 observed BGP neighbours.

Notable

• 23.161.32.0/24 is netname VC-DEN-V4-01, registered to Vertical Computers.
• 23.187.0.0/23 looks up as netname NET23, registrant American Registry for Internet Numbers — the registry's own parent record rather than an assignment.
• Two IPv6 /32s from different ranges, 2604:d2c0::/32 and 2620:1df::/32.
• 14 neighbours against 768 addresses.

Interesting

• When a lookup returns the registry as the registrant, what it usually means is that no more-specific record covers that block, so the query falls through to the /8 the registry holds for itself. The prefix is announced and routed either way; it is the paperwork underneath that has a gap in it.
• 2620::/23 is the range reserved for direct assignments to end-user organisations rather than to providers, so holding a /32 from it alongside one from ordinary provider space means the two were obtained by different routes, years apart.
• DEN in the netname is Denver, and V4 distinguishes it from the address family the company clearly expected to be labelling next.
