Summary
The George Washington University
education university research legacy
GWU belongs to The George Washington University, the private research university in Washington, D.C. It is a straightforward campus network: three IPv4 prefixes totalling about 131,000 addresses, two IPv6 /36s, and roughly 21 observed BGP neighbours.
What it's used for
This is the university's own enterprise and academic network — students, faculty, residence halls, administration, the medical and public-health schools, libraries and research groups all sit behind it. The address footprint is typical of a large US university that received a /16 in the early days of the commercial Internet and has never had to be frugal: 128.164.0.0/16 alone accounts for half the space, with 161.253.0.0/16 announced as two halves. A neighbour count in the low twenties is exactly right for a campus that multi-homes to commercial transit plus regional research and education networks, and it rules out any wholesale or transit role.
Notable
Both blocks are registered to the university itself, under the network handles GWU-GATE and GW-FENCE. Those are internal naming conventions, not separate organisations, and their presence is the useful negative result here: nothing in this AS is leased to or registered by a third party, so the space is unambiguously GW's own.
Interesting
Announcing IPv6 as two discrete /36s out of a 2606:69c0::/32-style allocation, rather than a single aggregate, suggests the v6 deployment is scoped to particular parts of the campus rather than rolled out network-wide.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
