NAME
  namepool - DHCP server database

DESCRIPTION
  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 allocated 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.

  FORMAT


  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 formats:
  domain  server
  domain  server  name_prefix

  The domain variable is the domain in which the names which follow are
  assigned.
  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
  exhausted.

  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.
