A server is getting IP Address from the DHCP server, and is given 30d lease time.
Assuming that the NIC is changed in the middle of the lease period (ie. the 2nd week), I would like to understand how DHCP works ..
a) after the change of the NIC, will the server receives the same IP address that was leased earlier (i.e. the lease has not expired).
b) Using the above scenario, will the client sends out DHCPDISCOVER packet or a DHCPREQUEST packet?
c) What does the DHCP packets contain ... the NIC MAC address? or the Computer name?
