AS13134 Instituto de Informatica, IP Ministerio da Solidariedade e Seguranca Social
Unclassified RIPE
Summary
Instituto de Informatica
government infrastructure enterprise
The longest AS handle in this range: a ministry's complete name, comma included.
What it's used for
- The IT institute of Portugal's social security ministry. 256 addresses in one IPv4 prefix, one observed BGP neighbour, and no IPv6 announced.
Notable
- The AS handle is the institute's full name followed by the ministry's, punctuation and all.
- The single prefix is
195.245.197.0/24, netnameII-MSSS-NET. - One of three sampled addresses returned a name:
chat.seg-social.pt. - One observed BGP neighbour.
Interesting
- The handle is the opposite failure to the entries in this range that shrank to a street or a city: where those dropped everything identifying, this kept everything, and both are unusable as short labels. The field has no length discipline, so it collects whatever was pasted into it.
- The netname abbreviates the same two organisations to six characters. One record, two answers to the question of how to name a government department, neither derived from the other.
- A chat service on a social security domain, on the one address that answered. Public bodies put citizen-facing services on small blocks like this and keep the case systems somewhere unrouted; the /24 is the shop window.

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 1,849 prefixes, as published 2026-10-30. 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.
