What is DHCP

DHCP is the English abbreviation of Dynamic Host Configuration protocol, the Chinese name is: The DHCP server Configuration Protocol, the main role is to assign IP address to the computer, the network device that runs the DHCP service is called to be in the office. PS: Ordinary computers, servers, routers, and so on can run the DHCP service.

Today's home routers have the ability to provide DHCP services, it can be said that the current home router is a DHCP server, DNS server, NAT server collection. By default, a router's DHCP server is started and does not require a user to configure it. Users only need to know that a DHCP server is used to assign IP addresses, DNS server addresses, and default gateway addresses to the computers that connect to the router.

If you want to use the IP address assigned by the router to the Internet, first you need to configure your computer's IP address and DNS server address to be automatically available, so that you can automatically obtain the corresponding address provided by the DHCP server above the router.

When will the DHCP service be used? Depending on your network environment, if the broadband operator assigns you a static IP address, then you do not need to use a DHCP server, and generally a larger enterprise client will use this network access scheme. But as an ordinary home user, most of the internet is used ADSL dial-up Internet and community broadband These two ways, whether ADSL dial-up or community broadband will be used to DHCP services, this time should be your computer IP address set to automatically get, otherwise you will not be able to normal internet.
