Most residential network routers receive a unique IP address within the ISP network. Within a local network, a DHCP server assigns a local IP address to each device. DHCP services exist for networks running Internet Protocol version 4 (IPv4), as well as version 6 . The IPv6 version of the DHCP protocol is commonly called DHCPv6.
The DHCP server will reserve an IP address (so anyone else asking for one is not granted this one) and it will send that IP address to the device along with a lease identifying how long the address will be valid. Normally, from this point, the device will respond by confirming the IP address with the DHCP server and the DHCP server finally ...
[1]: 1.9 Therefore, hosts search for a DHCP server on the network before assigning link-local addresses. In the automatic address configuration process, network hosts select a random candidate address within the reserved range and use Address Resolution Protocol (ARP) probes to ascertain that the address is not in use on the network. If a reply ...
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 unavailable. An IPv4 host otherwise uses its DHCP-assigned address for all communications, global or link-local.
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. The address is reserved for a limited time while the DHCP ...
