pymds is a simple, authoritative-only DNS server that has a simple module system for customizing how name resolution happens. The main motivation for starting this project was to create a simple system for building smarter DNS servers, capable of geography awareness, geographic load balancing, application aware load balancing, etc. Current modules implement standard behavior of using a file based DB to answer queries and to provide simple round-robin load-balancing across several servers by altering the order that IP addresses are returned.
