Summary

Utility Telephone

United States of America · AI-generated

residential isp cable dsl

The AS handle UTILITY-AS is held by Utility Telephone, Inc.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries pointing to utilitytelephone.net and netnames like UTILI-5-LSAN-001 and UTILI-5-STK-001.
  • With 41,728 IPv4 addresses announced against only 6 observed neighbours, the ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants include Utility Telephone, Inc., WPTI Telecom LLC, Rem Net Communications, and Call America Inc, reflecting a mix of owned and acquired or leased address space.
  • The inventory consists of 17 IPv4 prefixes and 1 IPv6 prefix, with the largest blocks being /19s in the 66.113.64.0 and 216.162.160.0 ranges.
  • The presence of Call America Inc netnames suggests historical consolidation or leasing of address space from other regional carriers.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
