Have a look at /usr/share/doc/initscripts/sysconfig.txt from the 
initscripts package:
--------------------------------
      PREFIXn=
       Network prefix.  It is used for all configurations except aliases
       and ippp devices.  It takes precedence over NETMASK when both
       PREFIX and NETMASK are set.
--------------------------------

)I've found that /usr/share/doc/initscripts/sysconfig.txt is a very 
useful resource when one is trying to understand/edit ifcfg-* files).
