DNS Server and Proxy Server
e DNS server has a host name, domain name of the email address, etc. in association with the IP address
information.
Communication is impossible if the other party is described by host name, domain name, etc. when the computer
or the scanner performs IP communication.
Queries the DNS server for that information and gets the IP address of the other party. is process is called name
resolution.
erefore, the devices such as computers and scanners can communicate using the IP address.
Name resolution is necessary for the scanner to communicate using the email function or Internet connection
function.
When you use those functions, make the DNS server settings.
When you assign the scanner's IP address by using the DHCP function of the DHCP server or router, it is
automatically set.
e proxy server is placed at the gateway between the network and the Internet, and it communicates to the
computer, scanner, and Internet (opposite server) on behalf of each of them. e opposite server communicates
only to the proxy server. erefore, scanner information such as the IP address and port number cannot be read
and increased security is expected.
When you connect to the Internet via a proxy server, congure the proxy server on the scanner.
Connecting to the Network from the Control Panel
