Summary
Yan Telecom
residential isp cable dsl
NADYMSS-AS is operated by Yan Telecom Ltd.
What it's used for
- The address space carries residential customer traffic, evidenced by reverse DNS entries pointing to
citylink.pro(e.g.,ip-93-170-126-254.citylink.pro) and netnames such asYAN-TELECOM-NETandRU-YANTELECOM. - The AS announces 3072 IPv4 addresses across 5 prefixes and maintains 27 observed neighbours, a ratio consistent with a regional access provider rather than a transit hub.
- Traffic consists of subscriber eyeballs for cable and DSL services, as indicated by the operator's classification as a Cable/DSL/ISP.
Notable
- Registrants are largely consistent with the announcer, with
Yan Telecom Ltdlisted for the majority of prefixes, whileCityLink Ltdappears as a registrant for the91.221.48.0/23block. - The address inventory is composed of five distinct IPv4 prefixes, including a /22 and four /23s, all located 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: 447 networks and 1,852 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.
