Summary

James Cook University

Australia · AI-generated

education university research

The AS handle JCU-AS-AP is held by James Cook University.

What it's used for

  • The space carries university infrastructure, evidenced by the reverse DNS record vlan1501.jcu.edu.au and the netname JCU-AU.
  • The inventory consists of a single IPv4 prefix, 137.219.0.0/16, totaling 65536 addresses, with 0 IPv6 prefixes announced.
  • With only 1 observed neighbour, the low ratio of addresses to peers indicates an internal academic network rather than a transit provider.

Notable

  • The RDAP registrant IRT-JCU-NET-AU and netname JCU-AU align perfectly with the announcer, confirming direct ownership by the university.
  • The address inventory is a single contiguous /16 block, typical for a large institutional campus network.

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.
