WSKT-81, registered to Highline School District and University of Washington Networks and Distributed. - The AS announces 256 IPv4 addresses across 1 prefix and maintains 2 observed neighbours, a ratio consistent with a small, self-contained institutional network rather than a transit or large-scale access provider.
- Traffic from this AS consists of internal network traffic for a public school district in King County, Washington, supporting administrative and educational operations across its campuses.
Notable
- The registrant data lists both Highline School District and University of Washington Networks and Distributed for the announced prefix, indicating a shared or historically allocated address space.
- The address inventory is minimal, consisting of a single contiguous /24 block with no IPv6 prefixes in the inventory.

Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-22, 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 1,779 prefixes, as published 2026-10-23. 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.
