Summary

CityLink Ltd

Russian Federation · AI-generated

isp residential russia

RELANT-AS is operated by CityLink Ltd.

What it's used for

  • The address space carries residential or small-business access traffic, evidenced by the reverse DNS record ip-91-210-206-254.citylink.pro and the netname RU-MSVYAZ associated with the registrant M Svyaz LLC.
  • The AS announces a single IPv4 prefix, 91.210.204.0/22, comprising 1024 addresses, with no IPv6 prefixes in inventory.
  • With only 2 observed routing neighbours, the low neighbour count relative to the address block size indicates an access or eyeball network rather than a transit provider.

Notable

  • The RDAP registrant for the announced prefix is M Svyaz LLC (netname RU-MSVYAZ), which differs from the AS holder CityLink Ltd, suggesting a relationship between the two entities or leased address space.
  • The inventory consists of a single contiguous /22 block, indicating a compact and focused address allocation.

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.
