The following is duplicated 14 times in that file with the exception of:
renew 5 2019/3/1 08:03:44;
rebind 5 2019/3/1 08:26:14;
expire 5 2019/3/1 08:33:44;
They change with each repartition. Is this normal? This is the first of
the 14 entries.
lease {
interface "em0";
fixed-address 192.168.0.101;
next-server 192.168.0.1;
option subnet-mask 255.255.255.0;
option routers 192.168.0.1;
option domain-name-servers 192.168.0.1;
option host-name "scorpio.seibercom.net";
option dhcp-lease-time 3600;
option dhcp-message-type 5;
option dhcp-server-identifier 192.168.0.1;
renew 5 2019/3/1 08:03:44;
rebind 5 2019/3/1 08:26:14;
expire 5 2019/3/1 08:33:44;
}
