at what point does a client send a unicast packet to the dhcp server to request a lease renewal for its current ip address?

A DHCP client submits a renewal request during the process, which is forwarded by a BIG-IP Forwarding IP type of virtual server to the particular DHCP server that provided the initial client IP address.The IP address lease for the client is then renewed by the DHCP server in a response. How does a DHCP server respond to an IP request that can be renewed?The DHCP client sends a unicast DHCP Request message to the DHCP server to request lease renewal when the lease has 50% (T1) remaining on its validity period.If a DHCP ACK message is received by the DHCP client, the IP address lease has been successfully renewed (counted from 0). This is a broadcast.They are all broadcast: DISCOVER, OFFER, REQUEST, and ACK.Before the entire procedure is finished, the client does not receive an IP address.Thus, it must be broadcast. The DHCPDISCOVER packet is sent by the client.The IP and DHCP parts of a DHCPDISCOVER packet are seen in the extract from a network monitor capture that follows.You can see that the Source address is 0.0 and the Destination address is 255.255.255.255 in the IP column. To get a DHCP-assigned IP address, type ipconfig /renew and hit Enter.To view all IP configuration details, type ipconfig /all.Keep an eye on the modified DHCP lease data.
