This method is also variously called static DHCP allocation, fixed address allocation, reservation, and MAC/IP address binding. An administrator maps a unique identifier (a client id or MAC address) for each client to an IP address, which is offered to the requesting client. DHCP servers may be configured to fall back to other methods if this ...
For link-local addressing, IPv4 uses the special block 169.254.0.0 / 16, [1] while IPv6 hosts use the prefix fe80:: / 10. More commonly addresses are assigned by a DHCP server, often built into common networking hardware like computer hosts or routers. Most IPv4 hosts use link-local addressing only as a last resort when a DHCP server is ...
ipconfig in Mac OS X serves as a wrapper to the IPConfiguration agent, and can be used to control the Bootstrap Protocol and DHCP client from the command-line interface. [8] 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]

On Windows XP, the server, by default, gets the IP address 192.168.0.1. (This default can be changed within the interface settings of the network adapter or in the Windows Registry .) It provides NAT services to the entire 192.168.0.x subnet, even if the address on the client was set manually, not by the DHCP server.

If a DHCP client outside the DHCP server's subnet broadcasts an address request, it is the helper that forwards the message to the DHCP server. The server then chooses an address and sends the client a unicast message, using the helper to send the message back to the client's subnet.
A NAP enforcement point is a computer or device that can evaluate a NAP client's health and optionally restrict network communications. NAP enforcement points can be IEEE 802.1X-capable switches or VPN servers, DHCP servers, or Health Registration Authorities (HRAs) that run Windows Server 2008 or later.
