PowerDNS is an open source DNS server software. It provides high performance with low memory requirements.
There are two types of PowerDNS nameserver:
1) Authoritative: Authoritative servers will answer about the domains it knows, but it does not resolve the queries about other domains.
2) Recursor: Recursor has no knowledge of the domains itself. It consults other authoritative servers to answer questions given to it.
