United States of America · AI-generated

education business us

The AS handle AMHERST-COLLEGE is held by Amherst College.

What it's used for

  • The space carries the institutional network for a private liberal arts college, identified by the netname AMHERST1 and registrant Amherst College.
  • The AS announces 16384 IPv4 addresses within a single prefix (148.85.192.0/18) and maintains only 1 observed neighbour, a ratio typical of a self-contained institutional network rather than a transit provider.

Notable

  • The RDAP registrant Amherst College aligns perfectly with the AS holder and the netname AMHERST1.
  • The address inventory consists of a single contiguous /18 block, representing a standard allocation for a mid-sized academic institution.

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 2026-11-02. 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.
