Summary

Mariana Islands Internet Exchange

Guam · AI-generated

exchange university guam infrastructure

The AS handle MARIIX-GU is held by Mariana Islands Internet Exchange.

What it's used for

  • The address space is registered to the University of Guam and its Office of Information Technology, with netnames explicitly identifying the MARIIX project.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix, maintaining only 2 observed neighbours, a ratio consistent with a local exchange point or route server rather than a transit provider.

Notable

  • Registrants for the announced prefix 103.115.192.0/24 include the University of Guam and its Office of Information Technology, aligning with the announcer's identity as a university-operated exchange.
  • The inventory consists of a single /24 IPv4 block and a single /48 IPv6 prefix, indicating a small, self-contained address estate dedicated to the exchange infrastructure.

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 1,773 prefixes, as published 2026-10-13. 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.
