nets(4)
NAME
  nets - JOIN DHCP server database

DESCRIPTION
  The nets file is employed by joind, the JOIN DHCP server to tell it which
  networks it is to administer and the ranges of IP addresses available for
  dynamic assignment on each of those networks.

  FORMAT


  Blank lines and lines beginning with "#" are ignored.	 Entries are
  separated from one another by newlines.  Entries consist of three fields:
  the network number (expressed as an IP address), the IP address or name of
  a host running joind, which dynamically configures clients on the network,
  and a range of available addresses for dynamic allocation to hosts on the
  net. The range is expressed as a pair of IP addresses with a dash, '-',
  between them. There must be no whitespace separating the dash from the IP
  addresses.

  Several servers may administer a single network, and a single server may
  administer several networks. Each Network-server pair may have several
  ranges of IP addresses available for dynamic allocation.  A useful
  shorthand is that the network and server IP addresses don't have to be
  repeated for each entry.  A line containing a single field is assumed to be
  an IP range with the same server and network as the previous entry: a line
  of two fields is assumed to be a server address and IP range with the same
  network as the preceding.

  The ranges of addresses served by each of the cooperating servers must be
  disjoint.  This condition is checked by the server on startup.
