Summary

Optinet

Bulgaria · AI-generated

isp residential bulgaria

OPTINETYAMBOL is operated by Optinet Ltd.

What it's used for

  • The address space carries residential and business internet access, evidenced by reverse DNS entries such as ip-254-203.optinet.bg and home-78-83-130-254.optinet.bg, and netnames including BTT and Optinet.
  • The AS announces 18,432 IPv4 addresses across 20 prefixes with only 3 observed neighbours, a ratio characteristic of an access network serving end-users rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs and residential broadband connections for Optinet's customer base in Bulgaria.

Notable

  • Registrants are consistent with the announcer, with Optinet Ltd listed for the majority of prefixes, though some blocks show A1 Bulgaria EAD and Neterra contacts as registrants, reflecting historical acquisitions or leased space.
  • The inventory is a mix of /20, /21, /22, /23, and /24 blocks, with the largest being 130.185.192.0/20.
  • No IPv6 prefixes are currently announced in the inventory.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-12, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 435 networks and 1,769 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.
