Currently the DHCPv6 protocol does not allow the provisioning of any routing-related information to hosts. A new proposal is addressing this shortcoming. The draft draft-ietf-mif-dhcpv6-route-option defines a mechanism for delivering routing information over the DHCPv6 protocol. This article explains core concepts and explains how to use the ISC DHCP software to deliver such information.
Dual Stack Lite is an architecture that allows IPv4 services to be provided in an IPv6 network, despite a limited amount of available IPv4 addresses. Work on DS-Lite was conducted within the Softwires working group in the IETF, and began in late 2008. After many revisions it was recently published as RFC6333, with its companion RFC6334 dedicated to automated configuration.
