Summary

Tivi.bg

Bulgaria · AI-generated

isp residential bulgaria access

The AS handle TIVI_ is held by Mitko.Com Ltd., operating as Tivi.bg.

What it's used for

  • The space carries residential and access traffic, evidenced by the reverse DNS record mt1-out126.tivi.bg and netnames BG-MITKOCOM-20180926 and Atlantis_BG_cust.
  • The AS announces 1536 IPv4 addresses and 38 IPv6 prefixes while maintaining 22 observed neighbours, a ratio consistent with a regional access provider rather than a transit hub.

Notable

  • Registrants align with the announcer, with Mitko.Com Ltd. listed for the primary prefix and Abuse-C Role for the secondary block.
  • The address inventory consists of two IPv4 prefixes and a large, contiguous IPv6 allocation under the 2a0d:9340::/47 range, indicating a modernized infrastructure.

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.
