Summary

Rostelecom

Russian Federation · AI-generated

telecom residential russia

ROSTOV-TELEGRAF-AS is operated by PJSC Rostelecom, specifically its Rostov-na-Don branch.

What it's used for

  • The address space carries residential and access traffic, evidenced by reverse DNS records pointing to donpac.ru (e.g., 0.104.254.80.donpac.ru) and netnames like Macroregional_South.
  • The AS announces 34,560 IPv4 addresses across 13 prefixes while maintaining only 2 observed neighbours, a ratio indicative of an access or eyeball network rather than a transit provider.

Notable

  • All registrants in the RDAP data are consistent with the announcer, listing PJSC Rostelecom and PJSC Rostelecom Technical Team.
  • The inventory consists of a mix of /19, /21, /22, /23, and /24 blocks, with no IPv6 prefixes currently announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-06, 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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
