Remarks

Due to distributed nature of Internet domains database, DNS servers are usually capable of immediate lookup of DNS records only for a limited subset of Internet domains. In order to lookup DNS records for domains belonging to external networks, a DNS server must be capable of DNS recursion which is a process of querying DNS server of higher level in the case when the current DNS server cannot find the requested resource in its local database. If the DNS server does not support recursion, it's practically useless since such server can serve only very restricted set of domains.
