1、递归模式，交互模式解析顺序在/etc/named.conf

There are two types of queries:
Recursive queries
Iterative (non-recursive) queries
The type of query is determined by a bit in the DNS query
Recursive query: When the name server of a host cannot
resolve a query, the server issues a query to resolve the
query
Iterative queries: When the name server of a host cannot
resolve a query, it sends a referral to another server to the
resolver
递归模式和反复模式。前者是name server 在不断地帮你找合适的server做域名解析；后者name server 返回一个合适的server referral需要你自己在做请求。后者resolver负载会大点。
