If your computer already has a fixed IP-address - for example if you have a cable modem, DSL or another permanent Internet connection - you may already be hosting a web-site on it. Why not also host DNS yourself for maximum control, including creating sub-domains etc. ? Even if you don't have your own domain name, Simple DNS Plus will speed up Internet access by caching all DNS records requested by your computer (or local network of computers), and fetching them again later much faster.
A secondary Simple DNS Plus server can be configured as a "slave" server, meaning that all updates on the primary server are automatically transfered to the secondary. This includes creating and deleting zones. (On other DNS server, you have to create and delete zones on both primary and secondary servers). Everything is completely automated - when changes are made in the Record Editor, Simple DNS Plus immediately notifies secondary servers and a Zone Transfer is initiated. Simple DNS Plus can also be configured as a standard secondary DNS server, and will then automatically check for updates on the primary server. As everything else in Simple DNS Plus, Zone Transfers are implemented according to the DNS standards (RFCs), and so it is 100% compatible with other standard DNS servers.
