Summary

CATNIX

Spain · AI-generated

education nsp regional research

CATNIX is operated by Consorci de Serveis Universitaris de Catalunya (CSUC).

What it's used for

  • The space carries academic and research traffic, evidenced by the netname CATNIX-NET and registrants including CESCA Network Operation Center and IRT-CESCA-CSIRT.
  • With 256 IPv4 addresses and 6 observed neighbours, the inventory supports a regional network service provider (NSP) role for Catalan universities rather than a large-scale transit or access network.
  • Traffic consists of institutional data, research collaborations, and academic services shared among associated entities in Catalonia.

Notable

  • Registrants align with the announcer, listing CESCA Network Operation Center, IRT-CESCA-CSIRT, and Consorci de Serveis Universitaris de Catalunya.
  • The address inventory is compact, consisting of a single IPv4 prefix 91.213.30.0/24 and one IPv6 prefix 2001:67c:137c::/48.

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.
