So, this will also allow the other devices to locate and then connect to it. Normally, this is an IP address that will also last for around 24 hours before it expires.
Now, This is due to the DHCP lease time. So, This will also allow a local network to reallocate IP addresses that are from devices. Now, you have been disconnect this for a while to other devices. Just by freeing up the IP addresses for some of the other devices that may connect. This will unless and you will give them a static IP.
Explain DHCP Lease Time & Should It Be Changed?
This will Unless otherwise specified, also having a typical network router that will also assume. So, that there are any of the other connections that will be made to it is temporary.
