Summary

Cityline

Russian Federation · AI-generated

isp russia small

The AS handle CITYLINE- is held by Cityline.

What it's used for

  • The space carries the netname CITYLINE-RU with registrant CITYLINE NOC.
  • The network announces 512 IPv4 addresses across 1 prefix (217.25.84.0/23) and maintains 2 observed neighbours.
  • The ratio of a single /23 block to two peers indicates a small-scale access or local ISP operation rather than a transit provider.

Notable

  • The RDAP registrant CITYLINE NOC aligns with the AS handle CITYLINE- and the registry holder CITYLINE-RU Chishko Evgeniy Nikolaevich.
  • The address inventory consists of a single contiguous /23 block in the Russian Federation.

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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
