education university research legacy

UMASSNET-AS1968 serves the University of Massachusetts, a public research university system with its flagship campus at Amherst.

What it's used for

  • Campus, research, and administrative networking across the university.

Notable

  • A university (institutional) network, not a commercial ISP or host.
  • The low AS number reflects an early-1990s allocation, from when major universities first connected to the internet.

Reputation

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
