Summary

12 bit LLC

Russian Federation · AI-generated

business russia small

The AS handle LLC12BIT-AS is held by 12 bit LLC.

What it's used for

  • The address space carries internal corporate or business traffic, indicated by the netname LLC12BIT and reverse DNS entries like lan-64-67-229-185.12bit.ru.
  • The network announces 256 IPv4 addresses across 1 prefix (185.229.67.0/24) with 1 observed neighbour, a ratio consistent with a small, self-contained business network rather than a transit or large access provider.
  • Traffic from this AS consists of internal corporate endpoints and services operated by 12 bit LLC.

Notable

  • The RDAP registrant 12 bit LLC matches the AS holder and the netname LLC12BIT, confirming consistent ownership.
  • The address inventory consists of a single /24 block, representing a compact and uniform allocation.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
