About this Tool

The DNS Hosting Speed tool will test how long it takes authoritative DNS servers to respond to a request for your domain or host, including the Domain, the TLD, and the Root DNS server response times.

This test provides you with information to help identify possible DNS hosting performance delays resolving your domain. It can be useful when evaluating the DNS performance of hosting providers, and general troubleshooting performance of a domain.

This test is run from our Test Source Location, in Reston, VA (USA), which is a secure hosting facility wholly separate from UltraDNS facilties. Server response times returned by this test are always relative to the Test Source Location.
