AS13917 — CORPWEST

AS13917 announces 5 IPv4 prefixes covering 4,096 addresses and 1 IPv6 prefixes.

About this network

Three addresses answered with three unrelated domains, one of them a bare domain with no host label at all.

What it's used for

• A regional hosting provider. 4,096 addresses across five IPv4 prefixes, one IPv6 prefix, and two observed BGP neighbours.

Notable

• Four blocks sit inside 66.206 under netname CORPWEST-1, registered to the announcer.
• The fifth is 206.14.125.0/24, netname NTTA-206-14, registered to NTT America, Inc.
• The reverse names that answered are alpha1dry.com, tpa.com and nunzio.netmagic.net.
• The IPv6 prefix is 2606:f000::/32.

Interesting

• A reverse record pointing at a bare domain rather than a hostname under it is a customer's whole domain resolving back to one address. That works, and it also means the address identifies the customer rather than the machine, which is the shape of hosting sold one server at a time.
• Three answers, three domains, no shared suffix: the provider never imposed a naming scheme, so each customer's reverse record says whatever they asked for.
• The IPv6 allocation is far larger than the IPv4 footprint. Registries hand out IPv6 by organisation rather than by need, so a provider with four thousand IPv4 addresses gets a prefix sized for a national carrier and uses a corner of it.
