Network type: hosting

AS12266 announces 1 IPv4 prefixes covering 4,096 addresses and 1 IPv6 prefixes.

About this network

A hosting network in Phoenix, Arizona, still registered under the name of a dot-com era shopping site.

What it's used for

• Customer hosting. One /20 of 4,096 addresses, one IPv6 /48, two observed BGP neighbours.

Notable

• The whole IPv4 inventory is a single announcement, 216.229.240.0/20, registered as SRN-HOSTING to StoreRunner, Inc.
• Both sampled addresses return the same reverse name, customer.phx.srnhosting.net — a wildcard covering the customer space, with phx for Phoenix.
• The only IPv6 announcement is 2001:470:2b::/48, out of Hurricane Electric's 2001:470::/32.

Interesting

• StoreRunner was a comparison shopping site of the late 1990s. The site is long gone; the corporation, its address allocation and its AS number are not, and the hosting business running on them today still answers to the old name in every registry that matters.
• A /48 from 2001:470::/32 is worth noticing. That range is Hurricane Electric's, and much of it was handed out through a free tunnel broker to anyone who asked, back when getting IPv6 from your own provider was not an option. Seeing one announced in BGP means an experiment that was never unwound.
• A single wildcard PTR across a whole customer block is the minimum-effort answer to reverse DNS. It satisfies the mail servers that check for one and tells an outside observer nothing.
