The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on Internet Protocol (IP) networks for automatically assigning IP addresses and other communication parameters to devices connected to the network using a client–server architecture.
It has a 2-byte DUID type field, and a variable-length identifier field up to 128 bytes. Its actual length depends on its type. The server compares the DUID with its database and delivers configuration data (address, lease times, DNS servers, etc.) to the client. Four DUID types are identified: [2]: §11 Link-layer address plus time (DUID-LLT)
Zero-configuration networking (zeroconf) is a set of technologies that automatically creates a usable computer network based on the Internet Protocol Suite (TCP/IP) when computers or network peripherals are interconnected. It does not require manual operator intervention or special configuration servers.
dhcpd (an abbreviation for "DHCP daemon") was a DHCP server program that operates as a daemon on a server to provide Dynamic Host Configuration Protocol (DHCP) service to a network. [3] This implementation, also known as ISC DHCP, is one of the first and best known, but there are now a number of other DHCP server software implementations available.
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 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.

To send and receive AOL email via a 3rd party email client, you'll need to manually configure the servers and port numbers with supported AOL Mail info. If you access AOL Mail through mail.aol.com or the AOL app you don't need to make any changes to your settings.
For example, you can release and renew an IP address if it happened to be assigned incorrectly by the DHCP server during the automated assignment process. [9] Like most Unix-based operating systems, Mac OS X also uses ifconfig for more direct control over network interfaces, such as configuring static IP addresses. The Ifconfig command in Linux ...
