Summary

Black Sea TV

Ukraine · AI-generated

business ukraine media

The AS handle BLACKSEA is held by TV Company "Black Sea" Ltd.

What it's used for

  • The address space carries corporate infrastructure for a Ukrainian television company, evidenced by netnames BLACKSEA-NET and reverse DNS entries like mitris.blacksea.net.ua and notuse.blacksea.net.ua.
  • The AS announces 4352 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, with only 3 observed neighbours, indicating a small-scale business or internal corporate network rather than a transit or large access provider.

Notable

  • Registrants are mixed: two prefixes are registered to LLC Renome-Service under netname UA-RENOME-SERVICE-20100830, while the other two are registered to TV Company "Black Sea" Ltd under netname BLACKSEA-NET.
  • The address inventory is finely subdivided into four distinct IPv4 blocks, suggesting site-by-site segmentation or separate operational units within the corporate estate.

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: 436 networks and 1,771 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.
