   At present it is a 32-bit unsigned integer.  So 4294967295 is the 
largest possible value (2^32-1, since it counts from zero).

   It is defined in src/lib/dhcpsrv/subnet_id.h in the code.

   I'm not aware of any.  It's supposed to just be an opaque identifier. 
There are plenty of people using "large" values here without complaint.
