- Use DNS : If your application needs the DNS function, click the select button and input the
domain name and the DNS Server IP address. Domain Name System (DNS) is a database system
that associates the Domain name with the actual IP address. The purpose of the DNS system is
to resolve the Domain name and represent it as an IP address. As a result, your device can
connect to an actual IP address.
- DNS Server IP: Input your DNS IP address or DNS server address provided by your Internet
Service Provider (ISP)
- Domain name : Input Domain name of connecting node. (Ex: www.wiznet.co.kr)
DNS function is good for peer IP that is not fixed (DHCP) or peer that have domain name. As a
result, you do not need to change peer IP configuration every time the peer IP change.
