       dhcp - Dynamic Host Configuration Protocol

       Dynamic	Host Configuration Protocol (DHCP) enables host systems in a TCP/IP network to be
       configured automatically for the network as they boot. DHCP uses  a  client/server  mecha-
       nism:  servers  store  configuration information for clients, and provide that information
       upon a client's request. The information can include the client's IP address and  informa-
       tion about network services available to the client.

       This manual page provides a brief summary of the Solaris DHCP implementation.

   Solaris DHCP Client
       The Solaris DHCP client is implemented as background daemon, dhcpagent(1M).

       For  IPv4, this daemon is started automatically during bootup if there exists at least one
       dhcp.interface file in /etc. Only interfaces with a corresponding /etc/dhcp.interface file
       are automatically configured during boot.

       For  IPv6,  this  daemon is started automatically when commanded by in.ndpd (based on IPv6
       Routing Advertisement messages). No /etc/dhcp.interface file is necessary, but such a file
       can be used to specify an interface as "primary," provided that IPv4 DHCP is also in use.

       Network	parameters  needed  for system configuration during bootup are extracted from the
       information received by the daemon through the use of the dhcpinfo(1)  command.	The  dae-
       mon's  default behavior can be altered by changing the tunables in the /etc/default/dhcpa-
       gent file. The daemon is controlled by the ifconfig(1M) utility. Check the status  of  the
       daemon using the netstat(1M) and ifconfig(1M) commands.

   Solaris DHCP Server
       The  Solaris  DHCP server is implemented as a background daemon, in.dhcpd(1M). This daemon
       can deliver network configuration information to either BOOTP or DHCP clients. The Solaris
       DHCP  service can be managed using the dhcpmgr(1M) GUI or the command line utilities dhcp-
       config(1M), dhtadm(1M), and pntadm(1M).

   DHCP Configuration Tables
       The Solaris DHCP server stores client configuration information in the following two types
       of tables:

       dhcptab tables	      Contain  macros  and  options (also known as symbols), used to con-
			      struct a package of configuration information to send to each  DHCP
			      client.  There  exists  only  one dhcptab for the DHCP service. The
			      dhcptab(4) can be viewed and modified using the dhtadm(1M)  command
			      or  dhcpmgr(1M) graphical utility. See dhcptab(4) for more informa-
			      tion about the syntax of dhcptab records. See  dhcp_inittab(4)  for
			      more information about the DHCP options and symbols.

       DHCP network tables    DHCP  network  tables,  which  contain mappings of client IDs to IP
			      addresses and parameters associated with those  addresses.  Network
			      tables  are  named  with	the IP address of the network, and can be
			      created, viewed, and modified using the pntadm command  or  dhcpmgr
			      graphical  utility.  See dhcp_network(4) for more information about
			      network tables.
