Mutsumi IWAISHI

This document summarizes and compares four DNS server software options: BIND, NSD, djbdns, and PrimDNS. It finds that BIND has the highest memory usage but fastest query times, while djbdns has the lowest memory usage but does not support DNSSEC. NSD and PrimDNS offer alternatives to BIND with lower memory usage and comparable performance.
