Unclassified RIPE
Summary
REG.RU
business registrar infrastructure
The AS handle AS-REG is held by REG.RU, a major Russian domain name registrar.
What it's used for
- The address space carries infrastructure for the registrar's operations, as indicated by the netname
RU-REGRU-940712and registrant "Reg.Ru Network Operations". - The AS announces 256 IPv4 addresses within a single /24 prefix (194.67.73.0/24) and maintains 22 observed neighbours, a ratio consistent with a business network requiring multiple transit or peering connections rather than a large access network.
- Traffic from this AS consists of web services, DNS infrastructure, and administrative endpoints supporting REG.RU's domain registration and hosting business.
Notable
- The RDAP registrant "Domain names registrar REG.RU", Ltd matches the AS holder, confirming consistent ownership of the announced space.
- The inventory is compact, consisting of a single contiguous /24 block with no IPv6 prefixes announced.

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 2026-10-13, 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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
