Summary

UVT Internet

Czechia · AI-generated

isp residential czechia cable

The AS handle UVT is held by UVT Internet s.r.o., a regional cable and DSL internet service provider based in Jesenice, Czechia.

What it's used for

  • The address space carries customer access traffic, as evidenced by reverse DNS entries such as cust-178.17.4.0.uvtnet.cz and cust.uvtnet.cz across multiple prefixes.
  • The network announces 7,424 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, while maintaining only 1 observed routing neighbour, a ratio characteristic of an access network rather than a transit provider.
  • Traffic from this AS consists of residential and small business subscriber data delivered via cable and DSL infrastructure in the Prague region.

Notable

  • All registrants for the announced prefixes are consistent with the announcer, listing UVT Internet s.r.o. and UVT Intenet - NOC for netnames including CZ-UVT-20100311 and CZ-UVT-20190402.
  • The address inventory is composed of five distinct IPv4 blocks of varying sizes, ranging from a /20 to a /24, all located in Czechia.

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.
