AS29744 UTMA - United Telephone Mutual Aid Corporation
Unclassified ARIN
Summary
United Telephone Mutual Aid Corporation
business telecom legacy
The AS handle UTMA is held by United Telephone Mutual Aid Corporation.
What it's used for
- The address space is primarily registered to United Telephone Mutual Aid Corporation with netnames like
UNITED-190-NETBLK-1andNET-66-231-120-0-1, indicating a corporate or legacy telecom estate. - One prefix,
216.196.64.0/21, is registered to Polar Communications with the netnamePOLARCOMM-BLK-2, suggesting a distinct operational segment or historical acquisition. - The AS announces 10496 IPv4 addresses across 8 prefixes and 1 IPv6 prefix, while maintaining only 1 observed neighbour, a ratio that implies an isolated or self-contained network rather than a transit provider.
Notable
- Registrants are largely consistent with the announcer, with United Telephone Mutual Aid Corporation holding the majority of the space, though Polar Communications appears as a registrant for a specific block.
- The inventory consists of a mix of /20, /21, /22, /23, and /24 blocks, reflecting a fragmented address allocation typical of older telecommunications infrastructure.

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: 449 networks and 1,846 prefixes, as published 2026-11-02. 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.
