       namepool - DHCP server database

       The  namepool database provides joind with names that are available for
       dynamic assignment to clients of the  DHCP  protocol.   For  each  DHCP
       server and domain name (NIS or DNS), the database contains a collection
       of names available for allocation to DHCP clients within those domains.
       One  name  plays a distinguished role - it is used as a prefix when the
       pool has been exhausted.	  Names	 are  generated	 from  the  prefix  by
       appending  a  number,  1,2..,  and a trailing 'd'. The namepool file is
       read whenever joind starts. Names within the database must not be allo‐
       cated to hosts which are not DHCP clients, and if the administration of
       a domain is shared between several DHCP	servers,  the  namepools  that
       each  has  must	be  disjoint.  Names may be added and removed from the
       namepool file.  If a name is removed from the file it remains bound  to
       the  client  to which it was allocated; if no such binding is in effect
       the name is excised from the server's pool the  next  time  the	server
       starts.	 Once  a  name is dynamically bound to a host it will never be
       reused even if that host subsequently acquires a new name, but there is
       no need to remove it from namepool.

       Blank  lines and lines beginning with a number sign (#) are ignored.  A
       new entry must begin in column one and has one of  the  following  for‐

       The  domain  variable is the domain in which the names which follow are
       The server variable is the name or IP address of the server  in	charge
       of allocating these names to clients.
       The  prefix  variable  is the prefix that will be used when the pool is

       Succeeding lines contain one or more names for domains that are	to  be
       allocated  by  the  server.   Each of these succeeding lines must begin
       with at least one white space character.
