config NET_DHCPV4_SERVER_ADDR_LEASE_TIME
int "Lease time for IPv4 addresses assigned by the server (seconds)"
range 0 4294967295
default 86400
help
Lease time in seconds for IPv4 addresses assigned by the server.
The lease time determines when the IPv4 address lease expires if the
client does not renew it.

config NET_DHCPV4_SERVER_ADDR_DECLINE_TIME
int "The time IPv4 addresses remains blocked after conflict detection (seconds)"
range 0 4294967295
default 86400
help
In case IPv4 address becomes blocked (either because of receiving
Decline message or due to ICMP probe detecting conflict), the address
can no longer be assigned. This timeout specifies how long the address
remains in the Declined state.
Note, that the server may try to reuse the oldest declined address in
case it runs out of free addresses to assign.

config NET_DHCPV4_SERVER_ICMP_PROBE_TIMEOUT
int "Timeout for ICMP probes sent by the server (miliseconds)"
range 0 60000
default 1000
help
DHCPv4 server will probe the offered IP address (send ICMP echo
request) and wait for the time specific by this config before offering
the address. If set to 0, ICMP probing will be disabled.
