Hosting RIPE Content
Summary
Citytelecom LLC
hosting legacy
CITYTELECOM-MSK is Citytelecom LLC, a Moscow-based telecommunications operator and RIPE NCC member providing connectivity and datacentre services in the Russian capital.
What it's used for
- Business internet access and hosting or colocation services in Moscow, carried over the operator's own network. The company peers at Russian exchange points and buys transit from a small number of upstreams.
Notable
- Mixed business-access and hosting address space rather than residential broadband, so addresses here are more likely to be servers and corporate connections than home users.
- The
-MSKsuffix in the handle marks this as the Moscow network, a common convention among Russian operators that number their regional networks separately. - Nothing in the record ties this holder to the early internet, so the low AS number should be read as a reassignment to a modern operator.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
