Summary

International Fair Plovdiv

Bulgaria · AI-generated

business exhibition corporate

The AS handle FAIR- is held by International Fair Plovdiv AD.

What it's used for

  • The address space carries corporate infrastructure for the exhibition venue, evidenced by reverse DNS records pointing to fair.bg and netnames FAIR and FAIR-BG-NET.
  • The network announces 512 IPv4 addresses across 2 prefixes with only 1 observed neighbour, indicating a small, isolated corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of office workers, exhibition visitors, and internal systems for the International Fair Plovdiv, a major exhibition organizer in Southeast Europe.

Notable

  • Registrants align with the announcer, with International Fair Plovdiv AD listed for the primary prefix and BTC IP ADDRESS SPACE administration for the secondary prefix.
  • The address inventory is compact, consisting of two /24 blocks, which fits the profile of a single-site corporate network.

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 1,781 prefixes, as published 2026-10-16. 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.
