A Brief Introduction of What DHCP Means

What does DHCP mean? DHCP is the abbreviation of Dynamic Host Configuration Protocol. This protocol allows the server to dynamically allocate IP address and the configuration information to the client. That is, the protocol used by computer to obtain configuration information. check for more:  spoto dumps website

The Concept of DHCP

We already have a rough understanding of the DHCP Protocol. It is actually a LAN network protocol, which refers to a range of IP addresses controlled by the server. When the client logs in to the server, it can automatically obtain the IP address and sub-net mask assigned by the server. It uses UDP Protocol to work. It has two main purposes: one is to automatically assign IP addresses to internal networks or network service providers, and the other is to give users or internal network administrators as a means of central management of all computers. DHCP allows a computer to be assigned an IP address without requiring the administrator to configure information about the computer in the server data. Generally, DHCP, as a service component of Windows Server, will not be automatically installed by the system by default. It needs to be manually installed and configured by the administrator.

The Role of DHCP

With so much has been talked about, what is the role of DHCP? DHCP is usually used in large-scale local area network environment. Its main function is to centrally manage and allocate IP address, so that the host in the network environment can dynamically obtain IP address, Gateway address, DNS server address and other information, and can improve the utilization rate of address.

DHCP Protocol adopts the client / server model, and the dynamic allocation task of host address is driven by the network host. When the DHCP server receives the address application information from the network host, it will send relevant address configuration and other information to the network host to realize the dynamic configuration of the network host address information. DHCP has the following functions: 1) be able to ensure that any IP address can only be used by one DHCP client at the same time. 2) be able to assign a permanently fixed IP address to the user. 3) be able to coexist with hosts that obtain IP addresses by other methods. 4) be able to provide services to existing BOOTP clients.

How does DHCP Allocate IP Addresses?

DHCP allocates IP addresses in three ways: automatic allocation, dynamic allocation and manual allocation. The DHCP server specifies a permanent IP address for the host. With the automatic allocation method, once the DHCP client successfully rents the IP address from the DHCP server for the first time, the addresscan be used permanently. With the dynamic allocation method, The DHCP server assigns an IP address with time limit to the host. When the time expires or the host explicitly gives up the address, the address can be used by other hosts. With the manual allocation method, The IP address of the client is specified by the network administrator. The DHCP server only tells the specified IP address to the client host. Among the three address allocation methods, only dynamic allocation can reuse addresses that are no longer needed by the client.
