Summary

Rusk Networks

Georgia · AI-generated

educational research residential

JSOPN-AS is operated by Rusk Networks, a small educational and research network in Georgia.

What it's used for

  • The address space carries a single IPv4 block 193.23.203.0/24 with netname RUSK-DE-IPv4 and registrant Evgenii Diakov; rusk.cat NOC, alongside three IPv6 prefixes.
  • With 256 IPv4 addresses and 3 IPv6 prefixes announced against only 1 observed neighbour, the network functions as a small, self-contained access or research network rather than a transit provider.
  • Traffic from this AS consists of research and educational endpoints associated with the rusk.cat and jsopn.com domains, serving a limited user base within Georgia.

Notable

  • The RDAP registrant Evgenii Diakov matches the registry holder RUSK-AS Evgenii Diakov, confirming consistent ownership of the announced space.
  • The inventory is minimal, consisting of one IPv4 prefix and three IPv6 prefixes, all located in Georgia.
  • The AS has been observed in routing tables since 2017, indicating a stable, long-running small-scale operation.

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: 446 networks and 1,852 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.
