I've seen some documentation using <prefix>::1 with either a global prefix or link-local (fe80::1). Anyone use either of these in production and have negative or positive feedback? fe80::1 is seductive because it is short and the idea of having the same default gateway configured everywhere might be simple. At the same time using the same address all around the network seems to invite confusion or problems if two interfaces with the address ever ended up in the same broadcast domain.
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
If you need them to co-exist, you can also do things like:
<prefix>::<10240-20480> - DHCP Pool
I'll note that 10240-20480 are not valid IPv6 suffixes and that you would need to represent that as <prefix>::<2800-5000> and would probably be better off to use something more like <prefix>::8:* as your DHCP pool. Owen
