Summary

BiaTV

Hungary · AI-generated

cable residential hungary isp

BIATV is operated by BiaTV (Biatorbagyi Kabeltv Kft.).

What it's used for

  • The address space carries residential cable television and internet access, evidenced by reverse DNS entries such as host-91-147-210-254.biatv.hu and netnames registered to BiaTV Network Administrator.
  • The AS announces 2048 IPv4 addresses across 3 prefixes with only 1 observed neighbour, a ratio characteristic of a local access network rather than a transit provider.
  • Traffic consists of subscriber eyeballs for the Biatorbágy region, supporting the company's cable TV and broadband services.

Notable

  • All registrants for the announced prefixes (91.147.208.0/22, 91.147.212.0/23, 94.248.168.0/23) are consistent with the announcer, listing BiaTV Network Administrator.
  • The inventory is a small, contiguous block of IPv4 space with no IPv6 prefixes 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.
