As the exhaustion of IPv4 address space leads to a shift to IPv6, we will enter a period of coexistence of IPv6 with an existing IPv4 network. This period will demand the supply of both IPv6 and IPv4 service to both IPv6 and IPv4 clients. This WG publishes guidelines that examine issues and solutions for the smooth transition of ISPs and ASPs to IPv6 and examine the baseline for an IPv6 Home Router.
