Summary

National Social Security Institute

Bulgaria · AI-generated

government public bulgaria nssi

The AS handle NSSI-AS is operated by the National Social Security Institute.

What it's used for

  • The address space carries internal government infrastructure, evidenced by the netname NN-NSSI and registrant IT Department; National Social Security Institute.
  • The AS announces 512 IPv4 addresses within a single prefix (193.25.162.0/23) and maintains 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.

Notable

  • The RDAP registrant IT Department; National Social Security Institute aligns directly with the registry holder and the AS name, confirming consistent ownership.
  • The National Social Security Institute was created in 1995 as a successor to the Head Office of Social Security and manages state social security in Bulgaria.
  • The inventory consists of a single contiguous /23 block with no IPv6 prefixes, reflecting a compact and stable address allocation for a specific public institution.

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 1,783 prefixes, as published 2026-10-17. 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.
