Hmmm...that sounds very nice - just adding that one
line and _nothing else_.  This system is a server
though, so how will that router know to give me the
same IP every time ?

Ok, yes, I think I would like to do it manually like
this.  I notice you do not have a ipv6 default route
statement there - is it not needed ?

Do I need to tell my provider that I am taking the /48
they gave me and using it with a /64 like that, or can
I just stick in the /64 and it will work fine ?

I assume that if I just want to keep things simple I
can just put /48 in place of your /64, right ?

Thanks a lot.
