This is like dynamic allocation, but the DHCP server keeps a table of past IP address assignments, so that it can preferentially assign to a client the same IP address that the client previously had. Manual allocation This method is also variously called static DHCP allocation, fixed address allocation, reservation, and MAC/IP address binding.
Kea is an open-source DHCP server developed by the Internet Systems Consortium, authors of ISC DHCP, also known as DHCPd.Kea and ISC DHCP are both implementations of the Dynamic Host Configuration Protocol, a set of standards established by the Internet Engineering Task Force (IETF).
The DHCP server then offers the "lease" of an IP address to the client, which the client is free to request or ignore. If the client requests it and the server acknowledges it, then the client is permitted to use that IP address for the "lease time" specified by the server. At some point before the lease expires, the client must re-request the ...
The DHCP server integrates with the DNS server and allows local machines with DHCP-allocated addresses to appear in the DNS. dnsmasq caches DNS records, reducing the load on upstream nameservers and improving performance, and can be configured to automatically pick up the addresses of its upstream servers.

MAC addresses need to be individually configured on the servers by an administrator. RARP is limited to serving only IP addresses . Reverse ARP differs from the Inverse Address Resolution Protocol (InARP), which is designed to obtain the IP address associated with a local Frame Relay data link connection identifier. [ 2 ]
Where no DHCP server is available to assign a host an IP address, the host can select its own link-local address. Using a link-local address, hosts can communicate over this link but only locally; Access to other networks and the Internet is not possible. There are some link-local IPv4 address implementations available:
The host broadcasts a request containing the node's IP address, and the node with that IP address replies with its MAC address. ARP has been implemented with many combinations of network and data link layer technologies, such as IPv4 , Chaosnet , DECnet and Xerox PARC Universal Packet (PUP) using IEEE 802 standards, FDDI , X.25 , Frame Relay ...
