3.2 DNS Server Address

The DNS server is mainly used to convert the domain name into a network-recognizable IP address. DNS server

address can be set, the domain name can be resolved when the local domain name server is not perfect, Users can also set
specific DNS server addresses as required. When the E830-DIO (ETH-2A) needs domain name resolution, it will submit
a resolution request to the set DNS server. The usage is more flexible and reliable.

In Static IP mode, the default DNS host address is 61.139.2.69 and the standby DNS server address is 192.168.4.1.

In DHCP mode, the DNS server address is automatically acquired. Module supports domain name server address can be
set.
