Summary
King County Library System
library government business other
The AS handle KCLS is operated by King County Library System.
What it's used for
- The address space carries library network infrastructure, evidenced by reverse DNS entries such as
nat40-0.net.kcls.organd the netnameKCLSIP4. - The network announces 8192 IPv4 addresses across 1 prefix (206.188.32.0/19) with 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or large-scale access provider.
Notable
- The RDAP registrant "King County Library System" matches the AS holder and netname, confirming consistent ownership.
- The address inventory consists of a single /19 block, which is finely subdivided for internal use across the library system's locations.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,773 prefixes, as published 2026-10-13. 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.
