Summary

ACSS - Administracao Central do Sistema de Saude, I.P.

Portugal · AI-generated

government health infrastructure pt

IGIF-AS is the autonomous system for ACSS - Administracao Central do Sistema de Saude, I.P., the Portuguese central administration of the health system.

What it's used for

  • The space carries internal government infrastructure, evidenced by the netname IGIF and registrant ACSS - Administracao Central do Sistema de Saude, I.P.
  • The AS announces 256 IPv4 addresses across 1 prefix with 1 observed neighbour, indicating a small, isolated internal network rather than a transit or access provider

Notable

  • The registrant ACSS - Administracao Central do Sistema de Saude, I.P. matches the AS holder, confirming direct ownership of the address space
  • The address inventory consists of a single /24 block (193.164.0.0/24), representing a compact and self-contained allocation for the institute's operations

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.
