Unclassified RIPE
Summary
Optizon Ltd
cdn business russia
The AS handle OPTIBIT-CDN is held by Optizon Ltd.
What it's used for
- The address space carries CDN infrastructure, evidenced by reverse DNS entries such as
cdn-ok-subnet.sibir-ix.ruandcdn-cdnnow-broadcast.sibir-ix.ru. - The network announces 256 IPv4 addresses and 1 IPv6 prefix, with 4 observed neighbours, indicating a small-scale content delivery or peering presence rather than a large transit or access network.
- Traffic from this AS consists of CDN edge nodes and broadcast services, supporting content delivery operations within the Russian Federation.
Notable
- The registrant for the announced prefix 185.161.34.0/24 is listed as OPTIBIT NOC; Optizon Ltd; Abuse-C Role, which aligns with the AS holder.
- The address inventory is compact, consisting of a single /24 IPv4 block and a /32 IPv6 prefix, typical for a specialized CDN or service provider.

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 1,784 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.
