.I Seconds
should be the minimum number of seconds since a client began trying to
acquire a new lease before the DHCP server will respond to its request.
The number of seconds is based on what the client reports, and the maximum
value that the client can report is 255 seconds. Generally, setting this
to one will result in the DHCP server not responding to the client's first
request, but always responding to its second request.
.PP
This can be used
to set up a secondary DHCP server which never offers an address to a client
until the primary server has been given a chance to do so. If the primary
server is down, the client will bind to the secondary server, but otherwise
clients should always bind to the primary. Note that this does not, by
itself, permit a primary server and a secondary server to share a pool of
dynamically-allocatable addresses.

If the \fIuse-lease-addr-for-default-route\fR parameter is true in a
given scope, then instead of sending the value specified in the
routers option (or sending no value at all), the IP address of the
lease being assigned is sent to the client. This supposedly causes
Win95 machines to ARP for all IP addresses, which can be helpful if
your router is configured for proxy ARP.
