United States · AI-generated

isp telecom business

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.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 453 networks and 1,846 prefixes, as published 2026-11-12. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
