Summary
CAAREN — Capital Area Advanced Research and Education Network
education research legacy
CAAREN is the Capital Area Advanced Research and Education Network, a regional research and education network operated by The George Washington University in Washington, DC.
What it's used for
- Serves as the capital area's research and education network, connecting GW and affiliated institutions to Internet2 and to the wider R&E ecosystem.
- Provides network services to schools, libraries, hospitals, government institutions and other research organizations across the District of Columbia, Northern Virginia and Maryland.
- Operated as a service by GW's Research Technology Services rather than as a commercial ISP.
Notable
- Because it is an R&E network rather than an eyeball ISP, its traffic skews toward institutional and research flows: campus connectivity, data-intensive science and inter-institutional links.
- The low AS number here is a reissue, not an early-internet allocation. ARIN registered it to GW in 2013, when CAAREN was being built out.
Interesting
- CAAREN gives a single university the role of regional R&E provider for the nation's capital, a model more often filled by a state-level consortium than by one institution.

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 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,784 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.
