Bulgaria · AI-generated

education university bulgaria

The AS handle UNI-PLOVDIV-AS is held by University of Plovdiv "Paisii Hilendarski".

What it's used for

  • The address space carries university infrastructure, evidenced by the reverse DNS record sid.uni-plovdiv.net and netnames such as BG-UNI-PLOVDIV-20080827.
  • The AS announces 768 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small-scale access network for the institution.
  • Traffic from this AS consists of student and staff access, academic research endpoints, and administrative services for the university.

Notable

  • All registrants for the announced prefixes are listed as "LIR manager; University of Plovdiv 'Paisiy Hilendarski'", consistent with the AS holder.
  • The address inventory is compact, comprising three /24 blocks and a single /29 IPv6 prefix, typical for a single-site educational 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: 453 networks and 1,848 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.
