Lightweight, simple, and fast master DNS server
sheerdns is a master DNS server whose zone records are stored on a one-record-per-file bases. Because of this, sheerdns is likely the simplest DNS to configure, use, update, and operate. It’s especially efficient for networks with frequent updates – serving DHCP, for example. Updates to the zones are immediate, and do not require restarting sheerdns.
SheerDNS is a good candidate for creating and RBL for mail, or web sites, as well as for providing DNS on embedded systems. Or anything else that requires a fast DNS, with very low overhead.
