No high availability or redundancy of the DHCP bindings. This could cause problems if the current DHCP server and default gateway fails. You also would want this same functionality for IPv4. As IPv4 address space becomes increasingly constrained, you will want to keep track of your DHCP scopes and determine if your lease time is adequate with the plethora of BYOD systems joining your networked environment.
This packet will also contain its hardware address MAC along with other configuration parameters such as, DNS servers, domain name, etc. The client then configures its network interface using this information. To one or more hosts with a unique, local hardware address all the time.
Not to one or more hosts with different global IP addresses in each boot-up. This means that static address management of individual systems is not easily automated by any DHCP client utilities: you need to write your own software to do it in shell or Perl script. This guide is targeted for Debian based servers running the following OSes: Debian 6, 7, 8, 9, Since this guide is aimed towards beginners, we will assume that you do not have any firewall enabled on your system yet, so you can reach the internet from within the LAN.
This is required in order to download and install required packages for your server. First, we have to make sure your package tree has the latest software versions. In a small business or home environment, the DHCP server can simply be the router, while in a larger business it might be a single dedicated computer or server.
By using a client-server model, a DHCP server becomes the host, while the device connected to the network is the client. As soon as the client makes a request to the network for an IP address, the host assigns an IP address taken from a list of available options it holds.
This then allows the communication between the device and the network to happen. Additionally, it's much easier to manage such a network because there's no heavy lifting - the server automatically assigns IP addresses so IT staff don't have to. IT staff can instead be tasked with carrying out more transformative tasks, rather than the mundane, but simple tasks that end up consuming a lot of manpower.
Other benefits of using a DHCP network include that there are less likely to be conflicts between devices. Because the server assigns IP addresses, rather than humans, it ensures no two devices are given the same. IP Address Management : If you decide against using a DHCP server, you'll instead need to make sure you have the resource and time to manually move clients to subnets without the need for human interaction at all. All the network information is passed to the client from the DHCP server, so no manual work is required at all.
Centralised network client configuration : If you need a range of different of configurations for each client, you can create client groups, so each has different set-ups according to your business's requirements. All of this information is saved in the DHCP data store and this is where the configuration can be changed to roll out to all clients, without having to change them manually.
Large network support : DHCP is especially advantageous to networks with millions of DHCP clients, as they can use the server over multithreading to process many client requests simultaneously.
