   8 .SH NAME
   9 dhcp \- Dynamic Host Configuration Protocol
  10 .SH DESCRIPTION
  11 .LP
  12 Dynamic Host Configuration Protocol (\fBDHCP\fR) enables host systems in a
  13 \fBTCP/IP\fR network to be configured automatically for the network as they
  14 boot. \fBDHCP\fR uses a client/server mechanism: servers store configuration
  15 information for clients, and provide that information upon a client's request.
  16 The information can include the client's \fBIP\fR address and information about
  17 network services available to the client.
  18 .LP
  19 This manual page provides a brief summary of the \fBDHCP\fR
  20 implementation.
  21 .SS "DHCP Client"
  22 .LP
  23 The DHCP client is implemented as background daemon,
  24 \fBdhcpagent\fR(1M).
  25 .LP
  26 For IPv4, this daemon is started automatically during bootup if there exists at
  27 least one \fBdhcp.\fR\fIinterface\fR file in \fB/etc\fR. Only interfaces with a
  28 corresponding \fB\fR\fB/etc/dhcp.\fR\fB\fIinterface\fR\fR file are
  29 automatically configured during boot.
  30 .LP
  31 For IPv6, this daemon is started automatically when commanded by \fBin.ndpd\fR
  32 (based on IPv6 Routing Advertisement messages). No
  33 \fB/etc/dhcp\fR.\fIinterface\fR file is necessary, but such a file can be used
  34 to specify an interface as "primary," provided that IPv4 DHCP is also in use.
  35 .LP
  36 Network parameters needed for system configuration during bootup are extracted
  37 from the information received by the daemon through the use of the
  38 \fBdhcpinfo\fR(1) command. The daemon's default behavior can be altered by
  39 changing the tunables in the \fB/etc/default/dhcpagent\fR file. The daemon is
  40 controlled by the \fBifconfig\fR(1M) utility. Check the status of the daemon
  41 using the \fBnetstat\fR(1M) and \fBifconfig\fR(1M) commands.
