Summary
RUBIT
business transit russia
RUBIT is the AS handle for RUBIT Limited Liability Company "Business information technology".
What it's used for
- The space carries business and research network traffic, evidenced by the netname
RU-ROSNIIROS-960103associated with the Autonomous Nonprofit Organisation "Russian Scientific-Research Institute for Public Networks". - With 512 IPv4 addresses announced across 2 prefixes and only 2 observed neighbours, the low neighbour count relative to the address space suggests a limited transit or interconnection role rather than a large-scale access network.
Notable
- Registrants do not fully align with the announcer; while one prefix is registered to the LLC itself, the other is registered to the Russian Scientific-Research Institute for Public Networks.
- The address inventory consists of two distinct /24 blocks, one under the LLC's direct control and one under a research institute, indicating a mixed or leased arrangement.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-21, 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: 442 networks and 1,779 prefixes, as published 2026-10-22. 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.
