I designed a network adapter board with Ethernet interface and lwip TCP/IP stack, with DHCP client enabled. It works well.

What happens if I disconnect the Ethernet cable from one network and connect it to a second network where is a different DHCP server? Mainly if the first network works on different address range (for example, 192.168.1.x and 192.168.2.x with 255.255.255.0 netmask).

I tried and it appears lwip/DHCP client doesn't trigger a new DHCP request and continue working with the first IP address... so it doesn't work on the second network.
