What is DHCP ack?

DHCP ACK, or DHCP Acknowledgment, is a message sent by a Dynamic Host Configuration Protocol (DHCP) server to a client after the client has requested an IP address and other network configuration settings. This message confirms the allocation of the requested IP address to the client, along with the duration of the lease and any additional parameters, such as subnet mask and default gateway. The DHCP ACK is a crucial part of the DHCP process, enabling devices to communicate on a network with the assigned IP address.
