Unclassified ARIN
Summary
University of Washington
education research infrastructure
A netname numbered seven, on a university's only block in this AS.
What it's used for
- A university's network. 2,048 addresses in a single IPv4 prefix plus
2607:4000:300::/40of IPv6, with one observed BGP neighbour.
Notable
173.250.224.0/21carries the netnameUW-SEATTLE-07, registered to the university with a security operations role contact.- The AS handle is
UW-GR-AS, with two letters in the middle that expand to nothing on their own. - Three addresses were queried for reverse DNS and none returned a name.
- The AS first appeared in routing on
2000-08-18.
Interesting
- The number on the end says this is the seventh record in a series, and only one of them is here. A university of this size holds address space across several AS numbers, so an inventory built from one of them shows a fragment and the netname is what tells you so.
- Naming a security operations team as the registry contact is considered practice at institutions that receive a steady stream of abuse reports about student machines. Most organisations name a generic mailbox that nobody reads.
- A
/40of IPv6 is a large allocation, and universities were among the earliest adopters because research networks needed the space before anyone else did. - One neighbour for a research institution is the shape of a campus that reaches the wider internet through a regional research network rather than by buying transit directly.

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.
