AS32027 POS-ASN
Unclassified ARIN
Summary
Port of Seattle
government port airport logistics
The AS handle POS-ASN is held by Port of Seattle.
What it's used for
- The address space carries internal network infrastructure for the port authority, with all four prefixes registered under the netname
NETBLK-POS. - The inventory consists of 3072 IPv4 addresses across 4 prefixes, with 0 IPv6 prefixes announced.
- With only 3 observed neighbours, the low ratio of addresses to peers indicates a small, self-contained corporate or municipal network rather than a transit or access provider.
Notable
- All registrants for the announced prefixes are listed as Port of Seattle, matching the AS holder exactly.
- The Port of Seattle operates Seattle-Tacoma International Airport and the city's seaport, explaining the need for a dedicated autonomous system for its diverse public assets.
- The address inventory is composed of four distinct IPv4 blocks within the 198.134.0.0/16 range, with no IPv6 allocation present in the inventory.

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 2026-10-27, 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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
