Summary

CentraCom

United States of America · AI-generated

residential isp fiber cable

The AS handle CENTRALUTAH is held by CentraCom (Central Utah Telephone, Inc.).

What it's used for

  • The address space carries residential and business access services, evidenced by registrants like CENTRACOM INTERACTIVE and netnames such as CENTR-50 and AFFIBER-NET-2.
  • With 69,632 IPv4 addresses and 111 IPv6 prefixes announced against 31 observed neighbours, the ratio indicates an access/eyeball network rather than a transit provider.

Notable

  • Registrants largely align with the announcer, including CENTRACOM INTERACTIVE, Central Utah Telephone, Inc., and CUT-NET, reflecting the operator's corporate identity.
  • CentraCom is the DBA of Central Utah Telephone, Inc., a telecommunications company providing fiber, cable, and wireless services in Utah.
  • The inventory includes a mix of /20, /21, and /22 prefixes, with some space registered to American Fiber INC. under the netname AFFIBER-NET-2.

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: 442 networks and 1,772 prefixes, as published 2026-10-15. 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.
