The Netherlands' .nl: 36.3 Million Hostnames, the Internet's First Country Code, and the Quiet Backbone of Everything
We parsed 36.3 million observed hostnames in the .nl namespace — rank #11 of 1,511 TLDs. ISP reverse-DNS from Ziggo, XS4ALL, and Chello accounts for a large share of them. The Netherlands — about 17.9 million people — registered the first active country-code domain in 1986, hosts the world's largest Internet exchange, headquarters RIPE NCC, and produced the DNS software that powers the global root. At roughly 2.03 observed hostnames per resident, .nl is the densest national namespace in Europe, and 71.7% of those hostnames return a live A record — well above the 58.9% whole-namespace rate. Refreshed June 2026 with first-party DNS resolution data.
