- You can use the first or last IP address in the specified CIDR block as the gateway.
- If left blank, the first IP address in the specified CIDR block is used as the gateway.
- DNS: Add a DNS server to provide domain name resolution services for the L3 network. You can specify 223.5.5.5, 8.8.8.8, or 114.114.114.114.
