How domains are attributed here

A domain counts towards Tucows / OpenSRS 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 June 2026, which ICANN publishes about three months in arrears; zone files contain no registrar information, so no fresher source exists.
