By understanding where IPv4-addresses are stored.

Do known that DHCP server **and also** the DHCP client
do try to keep the IPv4-address.  "try to keep" as in "keep assigned"(by
server) and "keep using" (by the client)

Manual page of DHCP-server dnsmasq ( `man dnsmasq` ) mentions:

  /var/lib/misc/dnsmasq.leases
  /var/db/dnsmasq.leases


Where the DHCP-client stores it's information, is up to the DHCP-client.
