GLC-SX-MM As the administrator must know this. DHCP Dynamic Host Configuration Protocol abbreviation, it is one kind of the TCP/IP protocol suite, the main network is used to assign dynamic IP client. These IP addresses are assigned a composed of a plurality of address of the DHCP server addressreserved sets, and they are generally a period of continuous address.
Understanding of DHCP services
The use of DHCP must have a DHCP server on the network, and other machines running the DHCP client. When the DHCP client sends a request message, a dynamic IP address,the DHCP server has been configured according to the present address, to provide anavailable IP address and subnet mask to the client.
1 advantages of using DHCP
DHCP enables the server to dynamically provide the IP address for the other servers in the network, by using DHCP, you can not give any server in addition to DHCP, DNS and WINS server outside the set up and maintain a static IP address in Intranet network. The use of DHCP can greatly simplify the configuration client TCP/IP work, especially when the change of some parameters of TCP/IP changes, such as large-scale reconstruction of the networkcaused by IP address and subnet mask.
The DHCP server is running Microsoft TCP/IP, DHCP server software and the Windows NTServer computer, the DHCP client is requesting TCP/IP configuration information of host TCP/IP. DHCP using the client / server model, the network administrator can create one or more maintenance configuration information for the TCP/IP DHCP server, and provide it to the client.
In the network configuration of the DHCP server has the following advantages:
The administrator can specify the TCP/IP parameter for the entire Internet general andspecific subnet, and can be defined using the parameters keep client address. ? provide credible security configuration. DHCP avoids configuration error caused by manual input values in each computer, can prevent the network address of the computerconfiguration conflict.
The DHCP server can greatly reduce the allocation cost overhead and reconfigure thenetwork computer time, the server can configure the additional configuration of all values in the assigned address leases.
The client does not need to manually configure the TCP/IP.
? the mobile client in the sub network, the old IP address automatically released to use again. At the start of the client again, DHCP server automatically for the client to re configure the TCP/IP.
? most router can transmit the DHCP configuration request, therefore, the Internet eachsubnet does not require the DHCP server.
Note: if you want to use a DHCP server to support across multiple router subnet, the routermay require hardware upgrades. The router must support RFC 1533, 1534, 1541 and 1542.
2 DHCP address allocation method
DHCP using the client / server mode, the network administrator to set up one or more DHCP servers, the server to save the TCP/IP configuration information can be provided to the clients. This information includes the effective configuration parameters, network customersassigned to a valid IP address pool of customers (including reserved for manual configuration of the server to provide the address), the lease duration.
If the TCP/IP computers on the network is set to obtain an IP address from the DHCP server,the computer has become a DHCP client. Start the DHCP client, TCP/IP configuration information it communicate with the DHCP server to receive necessary. The configuration information includes at least one IP address and subnet mask, as well as the lease and theconfiguration of the.
The DHCP server 3 for the DHCP client TCP/IP address allocation method:
? hand in hand in the distribution: distribution, network administrators in DHCP servermanually configure the DHCP client IP address. When a DHCP client request the network service, the DHCP server to manually configure the IP address to the DHCP client.
Automatic allocation: in automatic distribution, without the need for IP address manually assigned any. When a DHCP client to the DHCP server to the first IP address, this addressis permanently assigned to the DHCP client, and will not be allocated to other clients.
The dynamic allocation: when a DHCP client for the IP address to the DHCP server, DHCP server is temporarily assigned to the client IP address. As long as the lease expires, the address will be returned to the DHCP server, for other clients to use. If the DHCP client still needs an IP address to complete the work, you can ask another IP address. Dynamic allocation method is the only way to automate repetitive use of IP address, it for the time being connected to the DHCP client network is particularly convenient, good methodsfor the new host permanent and network connection is assigned IP address. The DHCP client will give up IP address when you no longer need, such as DHCP clients is closed properly, it can be released to the DHCP server IP address, and then the DHCP server toDHCP client IP address assigned to the application of IP address.
The use of dynamic allocation method can solve the IP address is not enough trouble, such as class C network can support only 254 hosts, the hosts on the network has more than 300sets, but if the net at the same time up to 200 users, if the use of manual allocation or automatic allocation will not solve this problem. And the dynamic allocation of IP address is not assigned to a client, GLC-LH-SM as long as there is a free IP address, the DHCP server can assign it to the client requests the address; when the client no longer need the IP address, the DHCPserver reclaims.
