Dynamic Host Configuration Protocol (DHCP) discover message. The source address is the address provided by the DHCP server upon query from the client

1. PC request the DHCP server for any available DHCP server

2. DHCP responds back saying that I can allocate or lease an IP address to you which is a source address

3. And once the client gets the DHCP server and its own ip from the dhcp server, then the client looks to connect some other server that server ip becomes the DESTINATION address

And the destination address is the address that client connects to the internet in order to get any required service
