Summary

State of Ohio

United States of America · AI-generated

government state ohio network

The AS handle NET-STATE-OHIO is held by the State of Ohio, specifically the Department of Administrative Services.

What it's used for

  • The address space carries state government infrastructure, evidenced by netnames like STOH-66-144 and STOH-156-63 registered to the Department of Administrative Services.
  • With 262,912 IPv4 addresses across 17 prefixes and only 1 observed neighbour, this is a large, self-contained internal corporate estate rather than a transit or access network.

Notable

  • Registrants align with the announcer, with the Department of Administrative Services holding the majority of the space.
  • One prefix, 208.108.224.0/22, is registered to the Broadcast Educational Media Commission under the netname ETECHOHIO, indicating a specific state agency allocation within the broader state AS.
  • The inventory is heavily subdivided, particularly in the 156.63.0.0/17 block, which is split into numerous smaller prefixes ranging from /19 to /24.

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.
