The main benefits of IPv6 include a practically limitless amount of IP addresses and auto configuration. From what I have read,ISP's will give customers entire blocks of public addresses. I'm hoping that those block assignments will be static as I don't feel like assigning a new addresses to things that need static IP's on my network such as my network printer if my block assignment changes(I could assign an additional FE80::/64 link local address, but that can be a slight annoyance to have to maintain multiple addresses on a device).
I hope that with a newer firmware revision, dlink will allow us to adjust the prefix length of the lan IPv6 address of the router to something smaller than /64 (yes, I know that going smaller than a /64 breaks auto configuration, but that's not critical for me) as I'm fearful that my ISP (Time Warner cable) will most likely not be kind enough to hand out a /48 or even a /56 block. The inability to adjust the lan prefix lenght will make it difficult to have multiple LAN segments.
