Russian Federation · AI-generated

isp residential russia cgnat

The AS handle BEIREL-AS is held by Beirel Telecom LLC.

What it's used for

  • The address space carries residential and mobile subscriber traffic, evidenced by reverse DNS entries such as isp-cgnat-pool-45-94-118-254.beirel.ru and public-cgnat-pool-185-150-154-254.beirel.ru, alongside standard host records like host-188-35-21-254.beirel.ru.
  • The network announces 7,168 IPv4 addresses across 6 prefixes and 1 IPv6 prefix, while maintaining only 3 observed neighbours. This high address-to-neighbour ratio indicates an access network providing last-mile connectivity rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs and mobile data, utilizing CGNAT pools to serve a large number of end-users from a limited address inventory.

Notable

  • All registrants for the announced prefixes are consistent with the announcer, listing BEIREL TELECOM NOC and Beirel Telecom LLC for netnames including BEIREL-TELECOM and RU-BEIREL-20190705.
  • The address inventory is composed of six distinct IPv4 blocks, including a /21 and five /22s, all registered to the same entity, indicating a consolidated corporate estate.

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.
