Summary

Linfield University

United States of America · AI-generated

education university small

The AS handle LC-647 is held by Linfield University.

What it's used for

  • The address space carries the university's internal network, identified by the netname LC-647 and registrant Linfield University.
  • The inventory consists of 256 IPv4 addresses in a single /24 prefix and one IPv6 /48 prefix, with only 2 observed neighbours, indicating a small, self-contained educational network rather than a transit provider.

Notable

  • The RDAP registrant Linfield University matches the registry holder and the AS handle, confirming consistent ownership.
  • The address inventory is minimal, comprising a single IPv4 block and a single IPv6 block, typical for a small private 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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
