ALTIA-AS is held by Altia Consultores S.A.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by reverse DNS entries such as 0-10-58-176.data.altia.es and netnames ES-ALTIA-20110603 and ES-ALTIA-20170404.
  • The AS announces 3072 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal IT services, consultancy operations, and development environments for Altia Consultores, a Spanish technology and IT services company.

Notable

  • Registrants for both announced prefixes are LIR ES.ALTIA - Network Operations Department; ALTIA CONSULTORES S.A., which aligns directly with the AS holder.
  • The address inventory is compact, consisting of one /21 and one /22 block, consistent with a single corporate entity managing its own IP space for internal use.

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: 455 networks and 1,849 prefixes, as published 2026-11-13. 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.
