There are 35,184,372,088,832 /48 sites in the current allocation
policies. When we run out of them we can switch to /56's for the
next 8th of the address space which give 9,007,199,254,740,992
additional sites.
Unless ISP's are exceeding wasteful (by rounding everything up to the
next largest nibble) we won't run out of sites for the foreseeable future.
The only place where we should be nibble aligning is at the site delegation.
ISP should be able to cope with none nibble alignments.
