isp telecom business

Sixty-nine prefixes, four different reverse-naming schemes, and one hostname with its first letter missing.

What it's used for

  • A regional broadband provider. 34,048 addresses across sixty-nine IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.

Notable

  • Netnames are VZGNI-PUB-5, VIS-BLOCK and VIS-72-64, all registered to the current brand but none containing its name.
  • Five of eighteen sampled addresses answered, under four different naming schemes.
  • 64.223.189.254 answers as static-64-223-189-254.man.east.myfairpoint.net, with a city and a region as labels.
  • 71.255.125.254 uses cncdnh.fast instead, a city and state code with a speed tier.
  • 71.181.5.254 answers as edia-71-181-5-254.static.ngn.east.myfairpoint.net, where the leading word has lost its first letter.
  • 71.168.126.254 sits under a different domain entirely, with the current brand in it.

Interesting

  • Four schemes across five answers is a network assembled from other networks, each generation leaving its own zone in place because rewriting reverse DNS for thirty thousand addresses buys nothing.
  • A label reading as a common word with the first letter shaved off is a template that trimmed one character too many, and it will stay that way until someone notices.
  • The provider's own name appears in exactly one sampled hostname and in none of the netnames, while the previous brand is in almost all of them.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
