A DHCP Server is a network server that automatically provides and assigns IP addresses, default gateways and other network parameters to client devices. It relies on the standard protocol known as Dynamic Host Configuration Protocol or DHCP to respond to broadcast queries by clients. Show
A DHCP server automatically sends the required network parameters for clients to properly communicate on the network. Without it, the network administrator has to manually set up every client that joins the network, which can be cumbersome, especially in large networks. DHCP servers usually assign each client with a unique dynamic IP address, which changes when the client’s lease for that IP address has expired. When to use a router/switch as your DHCP Server
The Benefits of a dedicated DHCP Server
Organizations that are beginning to implement IPv6 should migrate DHCP for IPv4 scope off the routers/switches and put them on a robust DHCP server infrastructure. This change will also mean that your organization would want to have DHCP operate the same for both protocols. Enterprise organizations will want to take advantage of the centralized dual-protocol DHCP server to provide IPv4 and IPv6 addresses to client devices.

When DHCP client Cannot contact DHCP server they will get the IP address?If a device is unable to get an IP address via DHCP, it will use an automatic private IP address from the address range 169.254.
Which type of DHCP message is sent from the client to ask to be assigned with the IP address that was offered by the server?This message contains the IP address that the server is offering to lease to the client and other information such as the subnet mask, gateway address, and DNS server. The DHCP client receives the DHCPOFFER message and sends a DHCPREQUEST message to the server, requesting that IP address.
What do you do when the client host Cannot obtain an IP address from the DHCP server?Procedure. Check whether a fault occurs on the link between the client and the DHCP server. ... . Verify that DHCP is enabled. ... . Check whether DHCP address allocation mode is set on the interface of the device. ... . Check whether addresses in the global address pool and the IP address of the interface are on the same network segment.. What IP address is assigned to the computer when the DHCP server is not available?For example, this could occur on a network without a DHCP server, or on a network if a DHCP server is temporarily down for maintenance. The Internet Assigned Numbers Authority (IANA) has reserved 169.254. 0.0-169.254. 255.255 for Automatic Private IP Addressing.
