  Obtain the address via DHCP. This takes the following options:
  .Bl -tag -width ""
  .It Fl w Ns , Ns Fl -wait
! Specify the time, in seconds, that the command should wait to obtain an
! address; or specify
! .Cm forever
! to wait without interruption.  The default value is 120.
! .It Fl 1 Ns , Ns Fl -primary
! Specify that the interface is primary.  One effect will be that
! .Xr nodename 4
! will serve as
! .Fl h Ns , Ns Fl -reqhost
! if that switch is not otherwise specified.
! .It Fl h Ns , Ns Fl -reqhost
! Specify the host name to send to the DHCP server in order to request an
! association of a Fully Qualified Domain Name to the interface. An FQDN is
! determined from
! .Ar hostname
! if it is "rooted" (ending in a '.'), or if it consists of at least three
! DNS labels, or by appending to
! .Ar hostname
! the value configured separately using either
! .Xr defaultdomain 4
! or
! .Xr resolv.conf 4 .
! N.b. that the DHCP server implementation ultimately determines whether and
! how the client-sent FQDN is used.
