4.2 Local network parameters

4.2.1 Local IP

STATIC (static IP ) : users can define configuration IP , subnet mask, default gateway, domain name resolution
server (D NS server);
DHCP (dynamic IP acquisition): The device logs in to the server to automatically obtain the IP address, subnet
mask, gateway address, and DNS server address parameters assigned by the server and configure them for use;

4.2.2 DNS ( domain name resolution )

When the user enters the domain name, the DNS server will be automatically queried, and the
DNS server will retrieve the database to obtain the corresponding IP address. In the static IP mode ,
the user can customize the domain name resolution server to resolve private domain name server
data . In this mode, the device automatically follows the domain name resolution server configured
by the routing device, and the user only needs to modify the DNS server of the routing device
without configuring the device.
