Summary
Colby College
education university legacy
AS6056 (COLBY) is the campus network of Colby College, a private liberal arts college in Waterville, Maine.
What it's used for
- Campus networking for a single college: academic and administrative systems, residence-hall and classroom connectivity, and the college's public-facing web services.
Notable
- Addresses here are institutional, not consumer. They belong to students, staff and campus systems rather than to an ISP's subscribers, so traffic from this range typically originates on a university campus.
- It announces exactly one prefix, the legacy
137.146.0.0/16— a full classful/16for a college of a few thousand students. That ratio of address space to headcount is the signature of an early-1990s academic allocation, made when addresses were handed out generously and NAT was not yet the norm.

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: 448 networks and 1,849 prefixes, as published 2026-10-30. 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.
