education university business

ANDREWS is the autonomous system for Andrews University, a private Christian university in Berrien Springs, Michigan.

What it's used for

  • The address space carries the university's institutional network, identified by the netname ANDREWS and registrant Andrews University.
  • The AS announces 65536 IPv4 addresses within a single /16 prefix (143.207.0.0/16) and one IPv6 prefix (2620:0:2be0::/48). With only 2 observed neighbours, the low neighbour count relative to the address block indicates a direct connection model typical of an enterprise or educational site rather than a transit provider.

Notable

  • The RDAP registrant Andrews University matches the AS handle ANDREWS, confirming consistent ownership of the address space.
  • The inventory consists of a single contiguous IPv4 block and a single IPv6 prefix, representing a standard internal corporate or academic estate without complex subdivision or leasing patterns.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
