NS-Global is a free secondary DNS service. If you run your own authoritative DNS server to serve zones and would like to improve performance, consider adding us as an NS record for your zone.

NS-Global is an anycasted DNS server, which means that we have several identical servers globally which all answer for the same IP address, making NS-Global a faster and more resilient service than a single site DNS server.

Signing up is simple; we have a sign up form where you can submit your zone and primary name server IP addresses. We don’t have user accounts or passwords, but just send a confirmation link to the RNAME email address in your zone’s SOA record and you’re all set!
