Summary

Cortex SP Computer

Spain · AI-generated

business spain small

The AS handle CORTEX is held by Cortex SP Computer, S.L.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname ES-CORTEX-20030114 and registrant Cortex SP Computer for both announced prefixes.
  • The network announces 768 IPv4 addresses across 2 prefixes with only 1 observed neighbour, indicating a small, self-contained business network rather than a transit or large access provider.
  • Traffic from this AS consists of internal corporate endpoints and services for the Girona-based computer company.

Notable

  • Registrants for both prefixes match the AS holder, listing Cortex SP Computer and CORTEX SP COMPUTER, S.L..
  • The address inventory is compact, consisting of one /23 and one /24 block, both located in Spain.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
