Summary

University of Massachusetts Lowell

United States of America · AI-generated

education university research

UMASS-LOWELL is operated by University of Massachusetts Lowell.

What it's used for

  • The address space carries university network traffic, identified by the netname ULOWELL and registrant University of Massachusetts - Lowell.
  • The AS announces 65,536 IPv4 addresses within a single prefix (129.63.0.0/16) and maintains 1 observed neighbour, a ratio consistent with an internal institutional network rather than a transit provider.
  • Traffic originates from the university's campus infrastructure, supporting academic, administrative, and research activities at the institution in Lowell, Massachusetts.

Notable

  • The RDAP registrant University of Massachusetts - Lowell aligns perfectly with the AS handle and the announced prefix.
  • The institution was formerly known as the University of Lowell, having adopted its current name in 1991.
  • The inventory consists of a single contiguous /16 block, typical for a large educational institution managing its own address space.

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
