The AS handle TELESYSTEMS is held by Telecommunication Systems LLC.
What it's used for

tscrimea.ru(e.g.,77.123.223.255.tscrimea.ru). - The network announces 25,088 IPv4 addresses across 4 prefixes while maintaining only 2 observed neighbours, a ratio characteristic of an access or eyeball network rather than a transit provider.
- Traffic from this AS consists of subscriber connections for the operator's regional service area, specifically serving the Crimea region as indicated by the domain suffix.
Notable
- Registrants for all announced prefixes align with the announcer, listing
Telecommunication Systems LLCunder the netnameRU-TELESYSTEMS-20061124andRU-TELESYSTEMS-20240722. - The address inventory is concentrated in the 77.121.0.0/16 and 77.123.0.0/16 ranges, with a smaller block in 194.39.0.0/16.

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
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: 446 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.
