Summary

Top Net BG

Bulgaria · AI-generated

isp residential bulgaria

TOPNET-AS is operated by Top Net BG LTD.

What it's used for

  • The address space carries residential or business internet access, evidenced by reverse DNS entries pointing to ip.btc-net.bg and the netname TOPNET_BG-1.
  • The AS announces a single IPv4 prefix, 95.43.114.0/24, comprising 256 addresses, with 3 observed routing neighbours.
  • Traffic from this network consists of subscriber internet access provided by a local Bulgarian ISP.

Notable

  • The RDAP registrant for the announced prefix is listed as "BTC IP ADDRESS SPACE administration," which differs from the AS holder name but aligns with the reverse DNS domain btc-net.bg, indicating the address space is administered by the same entity.
  • The inventory consists of a single /24 block, representing a small, self-contained address estate typical of a regional access provider.

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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
