The acknowledgement phase involves sending a DHCPACK packet to the client. v t e The Dynamic Host Configuration Protocol (DHCP) is a standardized network protocol used on Internet Protocol (IP) networks. While configuring your router for DHCP, you have the ability to enter the MAC addresses of your computers’ network cards and enter which IP address to assign them. his comment is here
What is a IP address? This value is expected to be unique for all clients in an administrative domain. Changes its state to RENEW.

The DHCP is controlled by a DHCP server that dynamically distributes network configuration parameters, such as IP addresses, for interfaces and services. Having said that though it adds an extra layer of failure to the system should the DHCP server fail and on cheap network equipment it is often the software side that The prefix length must be preceded by a forward slash(/). These attacks fall into three main categories: Unauthorized DHCP servers providing false information to clients. Unauthorized clients gaining access to resources.

That leaves the ranges from 2-99 and from 150-254 wide open, which is usually plenty for most home networks.So Which Is Better?DCHP provides true "plug and play" networking, but it can DHCPv6 was initially described by RFC 3315 in 2003, but this has been updated by many subsequent RFCs.
