Totd is a small DNS proxy nameserver that supports IPv6 only hosts/networks that communicate with the IPv4 world using some translation mechanism. Examples of such translation mechanisms currently in use are: * IPv6/IPv4 Network Address and Packet Translation (NAT-PT) implemented e.g. by Cisco. * Application level translators as the faithd implemented by the KAME project (http://www.kame.net). See faithd(8) on *BSD/Kame. WWW: http://www.vermicelli.pasta.cs.uit.no/ipv6/software.html
