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.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
