The following lists a number of important limits found in KIP.  Each
limit also has the relevant size, variable name, and module where the
space definition can be found.

o Space taken by ALL zones names: 256 bytes (256, azonenames,
glob.h).  Every zone name is stored as a pascal string so each one
takes strlen + 1 bytes of storage.

o Number of zones: 32 (NAZONES, azone, gw.h)

o Number of dynamic IP addresses: 32 (NIPDAD, ipdad, NIPDAD)

o Number of routes: 64 (NAROUTE, aroute, gw.h).  This includes all
routes configured from atalkatab and all acquired routes.
