Summary

United States · AI-generated

isp government legacy

A small Washington state network operator whose announcements are almost entirely the address space of Kitsap County government.

What it's used for

  • Carrying Kitsap County's network. Every one of the announced blocks is registered to Kitsap County under the netname KITSAP-COUNTY, with the county's own network administration listed as the contact.

Notable

  • The AS is registered to DT Micro but announces nobody else's space. This is the shape of a service provider that runs the network for a single large customer, rather than an ISP with a subscriber base of its own.
  • 55,000 addresses across 18 prefixes, all carved out of 146.218.0.0/16, against just two observed BGP neighbours. A county government end site with two ways in.
  • No IPv6 announced.

Interesting

  • Kitsap County sits across Puget Sound from Seattle and holds a full legacy class B, which is a lot of address space for a county of a quarter of a million people. Local governments that connected early got allocations sized to the era rather than to their population, and unlike companies they rarely have a reason to give any of it back.

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.
