From my research, various authorities have recommended that a single /64 be allocated to router loopbacks with /128s assigned on interfaces.

Yes, this is what I advocate for loopbacks.

I often use the first /64 for loopbacks. Loopbacks are often used for management, iBGP etc and having short and easy to read addresses can be helpful. Something like 2001:db8::1 is easier to remember and type correctly than e.g. 2001:db8:18ba:ff42::1 :)

Cheers, Sander

I concur. I think think some have gotten confused with the suggesting of allocating a /64 for *ALL* loopbacks versus allocating a full /64 per loopback. Loopbacks should be /128, but all loopbacks for a site should be within a single /64 (the first one for reasons others, including Sander have said. -Randy
