Summary

TransTeleCom

Russian Federation · AI-generated

residential isp russia access

SUTTK-AS is operated by Joint Stock Company TransTeleCom.

What it's used for

  • The address space carries residential and mobile access traffic, evidenced by netnames such as SUTTK-ORB-PPPoE and SUTTK-CHEL-Dynamic, and reverse DNS records pointing to in-addr.suttk.ru.
  • The AS announces 24,064 IPv4 addresses across 43 prefixes and 1 IPv6 prefix, while maintaining only 7 observed neighbours; this high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants for the largest prefixes consistently identify the holder as TTC NOC; Joint Stock Company TransTeleCom or SUTTK NOC; TTC NOC, aligning with the AS holder.
  • The address inventory is finely subdivided into numerous /22, /23, and /24 blocks, reflecting internal segmentation for different service regions or technologies within the corporate estate.

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 1,782 prefixes, as published 2026-10-16. 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.
