Summary

Comfort XXI Century Ltd.

Russian Federation · AI-generated

business russia small

IPSERVICE is operated by Comfort XXI Century Ltd.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netnames MediaComLtd-NET and RU-COMFORT associated with the announced prefixes.
  • The AS announces 1280 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, a ratio consistent with a small-scale business or internal corporate network rather than a transit provider.
  • Traffic from this AS consists of internal corporate endpoints and office workers, given the operator's identity as a limited liability company in the Russian Federation.

Notable

  • Registrants for the two prefixes are K Telecom Ltd; MediaCom Ltd. and Comfort XXI Century Ltd., indicating a mix of leased or historically acquired space alongside the primary corporate estate.
  • The inventory is composed of two distinct IPv4 blocks: 213.109.52.0/22 and 91.236.114.0/24, with no IPv6 prefixes announced.

Reputation

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 1,783 prefixes, as published 2026-10-17. 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.
