<hostname> Name of the client. May be supplied by autoconfiguration,
|
||||
but its absence will not trigger autoconfiguration.
|
||||
If specified and DHCP is used, the user provided hostname will
|
||||
be carried in the DHCP request to hopefully update DNS record.

Default: Client IP address is used in ASCII notation.
