DNS server
DNS is a decentralised service which assigns PC names or Internet addresses ( Domain
names ) and IP addresses to one another. A DNS server has to administer this information
for each server or each LAN with an Internet connection.
Normally your Internet provider provides you with a
DNS server which makes this
assignment when connection is made to the Internet. If necessary you can define the
DNS server to be used for the Internet connections manually.
ì
In the Advanced Settings – Internet menu, select DNS Servers.
ì
Activate the Use custom DNS servers function via the option On.
ì
Enter the IP addresses for your preferred DNS servers (Preferred DNS server and
Alternate DNS server).
ì
Click OK to apply the settings.
