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;
}
