Summary

Rostelecom

Russian Federation · AI-generated

telecom residential business russia

The AS handle INTFRM-AS PJSC Rostelecom is held by PJSC Rostelecom.

What it's used for

  • The address space carries Rostelecom infrastructure, evidenced by the reverse DNS record mail2.frame.ru and netnames RU-RTK-20060720 and RU-RTK-20021218.
  • The AS announces 5888 IPv4 addresses across 11 prefixes with only 1 observed neighbour, a ratio that indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants are consistent with the announcer, listing PJSC Rostelecom and PJSC Rostelecom Technical Team for all prefixes except 217.15.52.0/24, which is registered to IntInform NOC.
  • The inventory consists of 11 IPv4 prefixes with no IPv6 prefixes in the inventory.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
