Summary

Oficina Semat Data

Spain · AI-generated

business software spain

SEMAT is the autonomous system for Oficina Semat Data, SL.

What it's used for

  • The space carries the corporate network for a Spanish software company, as indicated by the netname ES-SEMAT-20180919 and registrant Oficina Semat Data, SL.
  • The AS announces a single IPv4 prefix, 194.32.132.0/22, comprising 1024 addresses, with no IPv6 prefixes in inventory.
  • With only one observed neighbour, the network functions as a small, isolated corporate estate rather than a transit or access provider.

Notable

  • The RDAP registrant Oficina Semat Data, SL matches the registry holder and the AS handle SEMAT.
  • The address inventory consists of a single contiguous /22 block, consistent with a standard corporate allocation for a small-to-medium enterprise.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, 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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
