Devices connecting to the internet all require a unique address, which is an IP address. The internet is not one central server sitting in some facility with billions of computers connecting to it every day. It is billions of computers connected to one giant global network. Almost every \u2013 if not every \u2013 household today has multiple devices, and they all access the internet simultaneously, through a router.<\/p>\n

\"What<\/p>\n

DHCP is part of the process that makes everything run smoothly without manual intervention. It handles the queries of devices asking to connect and use the gateway to access the internet.

What is DHCP Server<\/h3>\n

Dynamic Host Configuration Protocol (DCHP) is a networking protocol designed to assign IP addresses and other parameters to connecting devices. The dynamic part of DHCP refers to its ability to allocate available IP addresses dynamically.<\/p>\n

A DHCP server is part of the router that acknowledges the requests coming from devices for an IP address<\/a>. The DHCP server looks up the parameters, such as the default gateway, DNS server, IP address range, and assigns one within those parameters. It is completely automatic, so a network administrator does not require manual intervention.<\/p>\n

Without a DHCP server, the network administrator or the user who has access to the router at home would have to add devices and assign IP addresses manually. The problem with this approach is not only the effort required, but an IP mismatch must also be prevented. An IP address assigned to one device must not conflict with another on the network. Furthermore, as devices retire, the IP addresses have to be freed to make room for new ones. It, however, is not a concern for homes where the number of IP addresses available far outweigh the number of devices present. But, it is a concern for offices and college campuses where new devices are logging in every day.<\/p>\n

How to Configure DCHP for Home<\/h3>\n

It\u2019s easy to configure DHCP for home. As a prerequisite, you must have access to the router. If you have a modem, then this method does not apply because modems are incapable of routing functionality. The majority of people use the two terms interchangeably. You can learn about the differences between a modem and a router in our blog here<\/a>.<\/p>\n

It\u2019s unlikely that users today \u2013 except for a few \u2013 are running a modem with a single ethernet port. Internet Service Providers (ISP) offer devices with both modem and router functionality.<\/p>\n

You can easily access the device\u2019s interface for settings such as enabling or disabling a DHCP server, assign static IP for devices, bandwidth control, IP lease control, and more.<\/p>\n

Every manufacturer has a different visual interface for their routers, but menus should feel familiar across all of them.<\/p>\n
