Summary

Pronet Telekom

Bulgaria · AI-generated

isp residential bulgaria access

The AS handle PRONET-AS is held by Pronet Telekom Ltd.

What it's used for

  • The address space carries residential and business internet access, evidenced by reverse DNS entries such as 151.237.120.64.lozen.pronet.bg and generic *.pronnet.bg pointers.
  • The network announces 7936 IPv4 addresses across 5 prefixes in Bulgaria, with only 1 observed routing neighbour, indicating a local access provider rather than a transit hub.
  • Traffic from this AS consists of subscriber eyeballs and local business endpoints served by Pronet Telekom's regional internet service.

Notable

  • All registrants for the announced prefixes are listed as "Abuse-C Role" with the netname BG-PRONET, consistent with the announcer Pronet Telekom Ltd.
  • The address inventory is a contiguous block within the 151.237.96.0/20 range, subdivided into five smaller prefixes.

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 1,773 prefixes, as published 2026-10-13. 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.
