AS13673 — FAIRPO-3

AS13673 announces 3 IPv4 prefixes covering 1,280 addresses and 0 IPv6 prefixes.

About this network

The same city is spelled out in one netname and abbreviated in the next, and the one address that answers is still labelled dial-up.

What it's used for

• A regional broadband provider. 1,280 addresses across three IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.

Notable

• 209.105.162.0/23 is netname FAIRPOINT-MANCHESTER-209-105-162, with the city written in full.
• 216.227.78.0/23 is netname FAIRPOINT-MANCH-227-78, the same city cut short and the address trimmed to two parts.
• Both are registered to the former company name with an abuse contact appended after a semicolon.
• 209.105.165.0/24 is netname FAIRPOINT-NET5 and is registered to the current brand instead.
• One of nine sampled addresses answered, as dial-209-105-162-255.myfairpoint.net.

Interesting

• Two objects cut for the same city, by the same company, with the city spelled two ways and the address truncated to different lengths, is the clearest possible demonstration that netnames are typed by hand and never reconciled.
• The rebrand has reached one registry object out of three. The old name holds the two larger blocks and the new name holds the smallest, which is roughly the speed at which registry data follows corporate change.
• A hostname that still says dial-up, on space announced by a fibre provider, is a reverse zone nobody has needed to revisit since modems.
