Thanks, Washam, I got the intense debate. But for 6rd, the IPv4 address of the BR is recommended to use in the DHCP option. Thus, different options are recommended for different technologies. I want to know the reason. Using the similar method to do the similar thing is better, isn't it? So, shall we modify the specification of 6rd to use a FQDN for the BR configuration on CEs?

Hi, There was a debate between ip literal v.s. fqdn for this issue. Please search the old mail archive to check it out. If I recall correctly, a major argument would be, many ISPs prefer dns server to do load balancing over dhcp server.
