cable dsl isp regional

UNITEL-INC is operated by Unitel Inc.

What it's used for

  • The address space carries cable and DSL access traffic, as indicated by the netnames UNITEL-CGNT-NET-1 and UNITEL-ME-PRIMARY and the reverse DNS record 192.136.171.1.reverse.uninets.net.
  • The AS announces 12,288 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining only 3 observed neighbours, a ratio that implies a regional access provider rather than a transit carrier.

Notable

  • The registrants for both announced prefixes, UNITEL-CGNT-NET-1 and UNITEL-ME-PRIMARY, are listed as Unitel Inc, matching the AS holder.
  • Unitel Inc is a telecommunications provider founded in 1987, serving small and growing businesses in New England with hosted and on-site office phone systems and IT services.
  • The inventory consists of two distinct IPv4 blocks, a /19 and a /20, alongside a single /32 IPv6 prefix.

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.
