The Queries by Qtype plot shows the breakdown of queries by DNS query type:

• A - Queries for the IPv4 address of a name. Usually the most popular query type.
• NS - Queries for the authoritative nameservers for a particular zone. These are usually rare because end users (and their software agents) do not normally send NS queries. NS records are normally included in the authority section of every DNS message.
