A DUID consists of two parts: a two-octet type field, which identifies the ID as a DUID, followed by a variable number of octets that are unique to each device.Ī DHCP Client ID is a unique identifier for a computer or other device that obtains an IP address from a DHCP server, as opposed to getting the IP address from the manual configuration. It can be used to provision, or configure, network devices when their identities are not known at the time of configuration. There are three types of DHCP Client IDs: the DUID, the client-id, and the link-local address.Ī DHCP Unique Identifier (DUID) is the standard way to identify devices when obtaining an IP address using DHCP. How many types of DHCP Client IDs are there? The DHCP server uses the DHCP Client ID to identify individual devices that are connected to the network and assigns IP addresses to them. When you connect to a network, your system requests an Internet protocol configuration from a Dynamic Host Configuration Protocol server. The DHCP Client ID acts as the media access control (MAC) address for your device. The DHCP Client ID is composed of four hexadecimal numbers that are used to identify a device to provide basic network services.Ī DHCP Client ID is essentially a number that’s used by the Dynamic Host Configuration Protocol to identify your device. This identification can be found on the ARP/DHCP tab in the IP Configuration Settings of the Network Adapter Properties Window. What is a DHCP Client ID?Ī DHCP Client ID is also known as an IP Client ID. It maintains a list of the devices that have been assigned addresses and which addresses it has made available for assignment via DHCP. The DHCP server is responsible for making this happen. When a computer joins the network, it has to find an IP address that isn’t already in use on the network.
WHAT IS DHCP CLIENT ID TIVO WINDOWS 7
This article explains how you can set up your own DHCP server on Windows 7 or 8 to provide IP Addresses for devices on your local area network (LAN). Devices can also be assigned specific static IP addresses if they need them – but this is less common. When a device joins the network, it sends a request for an address to the server, which assigns one from its pool and returns it in return. Typically, a network administrator will assign a pool of available addresses to the DHCP server on the network’s router or access point. The DHCP protocol is the most common way that home and small office networks get their IP addresses.
