government business ohio

CUYAHOGA-COUNTY is operated by Cuyahoga County Information Services Center.

What it's used for

  • The address space carries internal county IT infrastructure, indicated by the netname CUYAHOGA-COUNTY-OHIO and registrant Cuyahoga County Information Services center; CUYAHOGA-IT-TEAM.
  • The AS announces 1024 IPv4 addresses across 1 prefix (208.90.52.0/22) and maintains 3 observed neighbours, a ratio consistent with a small, self-contained internal network rather than a transit or large access provider.
  • Traffic from this AS consists of office workers and internal services for Cuyahoga County, a major local government entity in the Cleveland, Ohio metropolitan area with over 5,500 employees.

Notable

  • Registrants align with the announcer, listing Cuyahoga County Information Services center and CUYAHOGA-IT-TEAM.
  • The inventory consists of a single contiguous /22 block, representing a finely subdivided internal corporate estate for county-wide IT operations.

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.
