Server
First, DHCP overview
DHCP is the abbreviation for the Dynamic Host Configuration Protocol (Dynamics host Configure Protocol). A DHCP server allows administrators to centrally assign and specify global and subnet-specific TCP/IP parameters (including IP addresses, gateways, DNS servers, and so on) for use throughout the network. The client does not need to manually configure TCP/IP, and when the client disconnects from the server, the old IP address is released for reuse, for example, you have only 20 legitimate IP addresses, and you manage 50 machines. As long as these 50 machines use no more than 20 servers for DHCP service, you will not have a shortage of IP address resources.
If conflict detection settings are configured, the DHCP server tries to ping the connectivity of each available address in the scope before providing the address in the lease to the client. This ensures that each IP address provided to the customer is not used by another non-DHCP computer that is configured with manual TCP/IP.
(If you only have one computer, and the extranet IP on the server, do not do LAN host, then this operation will not do) 1, open DHCP Manager. Choose "Start menu → program → admin tool →dhcp", the default, which already has your server FQDN (fully qualified domain name, fully qualified domains), such as "wy.wangyi.santai.com.cn." The following figure: 2, if the list does not have any servers, you need to add a DHCP server. Select "dhcp→ → add Server", choose "This server" and press "Browse" to choose (or directly enter) the server name "WY" (that is, your server name). 3, open the scope of the Settings window. First select the FQDN name, and then press the right key → new scope. 4, set the role of domain name. The "name" item here is only for hints and can be filled in with any content.
