For example, the local area network has an IP address for 192.168.0.1 computer, of course, through the IP address can communicate with other computers in the intranet; but if the computer wants to access an external Internet network, Then you

DHCP service: In order to more conveniently manage the IP address of the developer on the same LAN and the IP address of the server, it is best to arrange the server within a certain range of static IP (for example 192.168.0.200), Will (192.168.0.10-200) Provides dynamic IP for the developer client in scope. Suppose our primary server (192.168.0.200) and the secondary Development Server (192.168.0.201) use static IP, while providing 192.168.0.10-200 dynamic IP assignment services for the network

device. DHCP is used to assign IP addresses to even such as mobile devices, and the DHCP server is first installed. $:sudo Apt-get Install Isc-dhcp-server Edit */etc/dhcp/dhcpd.conf * files, as follows: Ddns-update-style none; Ignore client-updates; authoritative; Option Local-wpad Code 252 = text; Subnet 10.0.0.0 netmask 255.255.255.0 { #---Default gateway option routers 10.0.0.1; #---Netmask option subnet-mask 255.255.255.0; #---Broadca
