*  *** NOTE: changing this value requires a rebuild of NETTOOLS! ***
 *
 *  NOTE: The client hostname size is actually governed by 2 definitions:
 *      1) CFG_HOSTNAME_MAX (defined in netcfg.h)
 *      2) HOSTNAME_LENGTH (defined in dhcp.h)
 *  These two values must be consistent!  If one is changed, both must be
 *  changed.
 *
 *  RFC 2131 and 2132 do not clearly specify what the maximum size for this
 *  value should be.  255 was determined based on MSDN "Host Name Resolution for
 *  IPv4" on Microsoft's website (the size is 255 + 1 to make room for "\0"). 
 *  See notes for fix of CQ15114 for more details.
