This configuration sets up a DHCP server on VLAN1 with an IP pool that includes the range of 192.168.18.50 to 192.168.18.254, using a network mask of 255.255.255.0. The gateway for the network is set to 192.168.18.1 and the DNS server is set to 119.6.6.6, which will be provided to clients when they obtain an IP address from the DHCP server on this VLAN1 network segment.
Note: This configuration assumes that VLAN1 has already been configured on the switch or router, and that it has access to the internet via a connection through the default gateway at IP address 192.168.18.1 (which could be a router or firewall device). It also assumes that there are no conflicting static IP addresses in use within this subnet range, as these could cause problems for devices attempting to obtain dynamic IPs from the DHCP server on this network segment
