About this network

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-customers and reverse DNS entries like klient.tfnet.cz and nat126-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
