Summary
TFnet
isp residential czechia cable
TFNET is operated by TFnet s.r.o., a regional cable and DSL internet service provider based in the Liberec Region of Czechia.
What it's used for
- The address space carries residential and small business subscriber traffic, evidenced by netnames such as
TFnet-customersand reverse DNS entries likeklient.tfnet.czandnat126-e1-jirbac.tfnet.cz. - The AS announces 5120 IPv4 addresses across 7 prefixes and 1 IPv6 prefix, while maintaining 24 observed routing neighbours; this ratio of address space to peering partners is characteristic of an access network rather than a transit provider.
- Traffic from this AS consists of end-user internet access, including web browsing, streaming, and gaming, consistent with TFnet's business model of providing high-speed optical internet to local communities.
Notable
- Registrants for the largest prefixes are consistently
TFnet s.r.o.orAbuse-C Role, aligning with the AS holder. - The inventory is subdivided into multiple /22 and /23 blocks, reflecting site-by-site or customer-segmented allocation typical of a regional ISP managing distinct service areas.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
