Summary
Rostelecom
telecom residential access russia
The AS handle STC-AS is held by PJSC Rostelecom.
What it's used for
- The address space carries residential access traffic, evidenced by the reverse DNS entry
62.183.15.255.modem-pool.kuban.ruand netnames such asMacroregional_SouthandRADNET. - With 119040 IPv4 addresses announced across 74 prefixes and only 2 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.
Notable
- Registrants for the largest prefixes include
PJSC RostelecomandSTC Internet Center, both associated with the Rostelecom technical team, confirming alignment with the announcer. - The address inventory is finely subdivided into numerous /21 and /22 blocks, consistent with site-by-site segmentation within a large corporate estate.
- The AS was first seen in RIS in 2003, indicating a long-standing presence in the routing table.

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 1,781 prefixes, as published 2026-10-16. 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.
