Summary

Communications Etc., Inc.

United States of America · AI-generated

business corporate us

COMETC1 is the AS handle for Communications Etc., Inc.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname ATTWORLD-MIS-229-216 on 12.229.220.0/24 and TRANSITION on 23.157.248.0/24.
  • The AS announces 512 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, isolated corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate communications and services for Communications Etc., Inc., a Texas-based entity.

Notable

  • Registrants differ from the announcer: 12.229.220.0/24 is registered to AT&T Services, Inc., while 23.157.248.0/24 is registered to Communications Etc., Inc.
  • The address inventory is small and subdivided, consistent with an internal corporate estate rather than a public-facing service network.

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: 447 networks and 1,848 prefixes, as published 2026-10-31. 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.
