Unclassified ARIN
Summary
City of Kirkland Washington
government municipal network
The AS handle CKW-3 is held by City of Kirkland Washington.
What it's used for
- The address space carries municipal network traffic, with the sole announced prefix 76.191.73.0/24 registered under the netname
WAVE-V4-2by Wave Broadband. - The inventory consists of 256 IPv4 addresses across 1 prefix, with 0 IPv6 prefixes announced.
- With 3 observed neighbours, the low neighbour count relative to the single /24 block indicates a small-scale access or internal network rather than a transit provider.
- Traffic from this AS represents city government operations, including administrative offices, public services, and municipal infrastructure within Kirkland, Washington.
Notable
- The RDAP registrant for the announced prefix is Wave Broadband, which differs from the AS holder City of Kirkland Washington, suggesting the address space is leased or managed by a third-party provider.
- The address inventory is minimal, consisting of a single /24 block, which is typical for a municipal network that does not require large-scale public address allocation.

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: 455 networks and 1,849 prefixes, as published 2026-11-14. 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.
