I don't think the industry has really found a best practice to document yet. There are people trying different ideas. We find the following convention allows us to keep things organized: <prefix>::1 - Default gateway <prefix>::<last octect IPv4> - Statically assigned servers. <prefix>:<eui-64> - Auto-configured host
This is essentially what we do (except we use the hex value of the last octet, so .34 would be ::22, probably just the purist in me). If you have an environment where hosts will be statically configured, then you probably want to use a global default, if only to avoid confusion from users or poorly written software that expects the default to be in the same prefix as the address. If people understand their prefix is 2001:DB8::/64, and the gateway is 2001:DB8::1 it raises a lot less questions than "your prefix is 2001:DB8::/64 but your default router is FE80...". -- Ray Soucy Epic Communications Specialist Phone: +1 (207) 561-3526 Networkmaine, a Unit of the University of Maine System http://www.networkmaine.net/
