Check my DHCP lease? Is there a way to show my current (client) DHCP lease? Or even better - retrieve all options/infos sent with `DHCPACK`?

I used `dhcpdump` when I was testing DHCP. It will dump both sides of the DHCP transaction. If you leave it running it will log the options passed.

You may want to restart your DHCP client to see the initial negotiation. The renewal request should contain all the running configuration.
