Are you in the process of selecting a DNS provider? CloudHarmony enables you to measure DNS query resolve time for a range of DNS services. Services include Akamai, Easy DNS, Google Cloud, DigitalOcean, NS1, IBM Cloud, Microsoft Azure, Oracle Cloud Infrastructure, Neustar, Rage4 Networks, to name a few. In the test shown above, we selected ten DNS service providers and got the results in less than two minutes.
How does CloudHarmony perform a DNS query test?
CloudHarmony uses two types of DNS query tests.
Recursive DNS query test. This test uses a client’s designated DNS resolvers to query an uncached DNS record. Such queries will propagate up a recursive chain to an authoritative DNS server. A wildcard name (A) record and random hostnames are used to force full recursive lookups during each test iteration.
Authoritative DNS query test. This test bypasses the recursive chain by querying authoritative DNS servers directly. During test initialization, authoritative servers are determined using a nameserver (NS) lookup. Every authoritative server is queried during a test iteration. Authoritative queries are generally faster than recursive as they require fewer steps.
