Summary

Agentia Spatiala Romana

Romania · AI-generated

government space research

The AS handle ROSA-AS is held by Agentia Spatiala Romana.

What it's used for

  • The address space carries the netname ROSA registered to Agentia Spatiala Romana, indicating a dedicated government agency network.
  • The inventory consists of 512 IPv4 addresses within a single prefix 194.116.136.0/23, with 0 IPv6 prefixes announced.
  • With only 2 observed neighbours, the network operates as a small, isolated endpoint rather than a transit or access provider, consistent with a specific institutional site.

Notable

  • The RDAP registrant Agentia Spatiala Romana matches the registry holder and the AS name ROSA-AS.
  • The address inventory is a single contiguous /23 block, representing a compact and self-contained estate for the agency's operations.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-20, 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: 442 networks and 1,779 prefixes, as published 2026-10-21. 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.
