Summary

Russian Federation · AI-generated

residential isp russia access

ASI-AS PJSC Rostelecom. Astrakhan branch is operated by PJSC Rostelecom, the largest integrated digital services provider in Russia.

What it's used for

  • The address space carries residential broadband access, evidenced by reverse DNS entries such as pppoe-5-139-194-0.astranet.ru and netnames like Macroregional_South.
  • With 21,248 IPv4 addresses announced across 14 prefixes and only 3 observed neighbours, the high address-to-neighbour ratio indicates an access/eyeball network rather than a transit provider.

Notable

  • All registrants for the largest prefixes are listed as PJSC Rostelecom Technical Team, which aligns with the announcer ASI-AS PJSC Rostelecom.
  • The address inventory is finely subdivided into multiple /21, /22, /23, and /24 blocks, consistent with internal corporate segmentation for a large regional operator.
  • The AS has been observed in routing tables since 2005-08-16.

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 1,784 prefixes, as published 2026-10-19. 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.
