IONOS / 1&1

Registrar DNS Serves 663,505 new-gTLD domains across 478 TLDs, 1.78% of all domains whose nameservers we can attribute. www.ionos.com/

The registrar's own nameservers, used by default for domains that have not been pointed elsewhere — which includes both active sites and domains doing nothing at all.

How domains are attributed here

A domain counts towards IONOS / 1&1 when one of its nameservers ends in one of these suffixes. Matching is on the name in the zone's NS records only — nothing is resolved or fetched. Listed by weight, which is the order the classifier tries them in so a specific suffix beats a broader one.

Data currency. Domain counts on this page are from zone files dated and refresh daily. Registrar figures are from ICANN's monthly registry reports for July 2026, which ICANN publishes about three months in arrears; zone files contain no registrar information, so no fresher source exists. Full detail on methodology and live pipeline status.
