Summary

Varna Net

Bulgaria · AI-generated

isp regional residential bulgaria

VARNANET-AS is operated by Varna Net Ltd.

What it's used for

  • The address space carries residential and local business traffic, evidenced by reverse DNS entries like UNNAMED.Varna.Net and UNNAMED.varna.net.
  • The AS announces 4352 IPv4 addresses across 2 prefixes and maintains 8 observed neighbours, a ratio consistent with a regional access provider serving the Varna area.

Notable

  • Registrants align with the announcer, showing Neterra Ltd. for the larger block and Varna Net NOC for the smaller block, indicating a unified operational entity.
  • The inventory consists of two distinct IPv4 prefixes: a /20 block and a /24 block, with no IPv6 prefixes currently announced.

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.
