However, this system has high requirements on system configuration. Therefore, we have recently eliminated more than 30 old computers and bought several hundred yuan for employees as benefits. On the DHCP server, the author sets the

If the router cannot run as a DHCP/BOOTP relay proxy, each subnet must have a DHCP server or another computer running as a relay proxy on this subnet. When you

Dynamic Host Control Protocol (DHCP) provides a convenient way for network administrators to provide network layer addresses for changing network hosts or dynamic networks, the most commonly used DHCP service tool being iscdhcpserver. The purpose of the DHCP service is to provide the host with the necessary network information to communicate with other hosts conn

If any server cannot be contacted, the customer system can continue to makeWith the previously assigned network parameter settings until the lease time period previously negotiated by the customer system expires, after the lease expires, or the customer systemThe initial

DHCP servers are usually used in network construction. In order to better understand this aspect, we will give a detailed introduction to the running principle and process of the DHCP address configurations implementation method.
