Summary
TDC (TDC Holding A/S)
isp eyeball legacy
TDC (TDC), Denmark's incumbent telecom operator, and one of the country's
largest networks with several million IPv4 addresses.
What it's used for
- Fixed broadband, mobile and TV services to Danish households and businesses, plus the national backbone that carries them.
- The bulk of this address space lands on residential subscribers, making 3292 a classic "eyeball" network.
Notable
- TDC traces back to 1879 as Denmark's national telephone company. It was split in 2021 into TDC NET (the physical fibre, coax and mobile infrastructure) and Nuuday (the consumer and business brands such as YouSee and Telmore), both under TDC Holding.
- With that scale of address space, TDC is the network most Danish consumer traffic originates from.
Interesting
- The low four-digit AS number reflects how early the Danish incumbent joined the commercial internet, well before the mid-1990s land rush pushed numbers into five digits.
