Tips of the Trade
DNS admins who need a secure, robust, high-performance authoritative DNS server should take a look at PowerDNS. PowerDNS operates differently from any other DNS server. It uses a database back end, which offers a number of advantages: lightning-fast performance, immediate changes and no restart requirement, and you can take advantage of database tools for replication and data integrity. It also reads plain-text zonefiles and LDAP directories. Ace programmers can make use of the Backend Developers Kit to access nearly any data source. If you have a batch of BIND zonefiles to migrate, use the included Zone2sql migration utility.
Supported databases include MySQL, PostgreSQL, Oracle 8i, Oracle 9i, IBM DB2, and Microsoft SQLServer. PowerDNS runs on FreeBSD, Linux, Mac OS X and Windows 2000/XP. PowerDNS is free, and paid support is available.
PowerDNS is standard-compliant (RFC 1034 and 1035) and supports all DNS record types. It is IPv6-ready and supports server monitoring. It presents no mysteries, you can see exactly where any problems and performance bottlenecks are.
PowerDNS itself is fairly simple to administer, and you don't need to be an elite database whiz to it get up and running, especially if you use MySQL. It includes a caching/recursive nameserver component, but it's rather immature, so a good scheme is to use PowerDNS for your authoritative server, and dnscache for a caching/recursive nameserver. See Powerdns.com for downloads and howtos.
