Summary

Sistemas de Seguridade A1 SL

Spain · AI-generated

security business spain

The AS handle SEGURIDADE_A1 is held by Sistemas de Seguridade A1 SL.

What it's used for

  • The address space carries infrastructure for a Spanish security equipment provider, as indicated by the registrant name and netname ES-SISTEMASA1-20180117.
  • The network announces 1024 IPv4 addresses across 2 prefixes with only 1 observed neighbour, indicating a small, self-contained business network rather than a transit or large-scale access provider.
  • Traffic from this AS consists of corporate endpoints and web services for the security systems company, not residential subscriber traffic.

Notable

  • The registrant Sistemas de Seguridade A1 SL matches the AS holder and the netname ES-SISTEMASA1-20180117 for both announced prefixes.
  • The address inventory consists of two contiguous /23 blocks (185.242.48.0/23 and 185.242.50.0/23), forming a single /22 range.

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.
