FRITZ!Box 7330 66
DNS Server: Freely Selectable
12.7 DNS Server: Freely Selectable
DNS servers are preset in the FRITZ!Box for IPv4 and IPv6.
These are the DNS servers assigned by the Internet service
provider.
For both IPv4 and IPv6, the preset DNS server can be replaced
by a free DNS server. Free DNS servers include, for instance,
OpenDNS and Google DNS.
Here is how to change the DNS server entry:
1. Open the FRITZ!Box user interface.
2. Enable the advanced view.
3. In the “Internet / Account Information” menu, select the
“DNS Server” page.
4. Change the settings for the DNS servers.
12.8 DNSSEC: Security for DNS Queries
DNSSEC is short for Domain Name System Security Exten-
sions. As the name says, this is an extension of DNS, the
domain name system.
DNSSEC ensures that both the DNS server and the informa-
tion returned by the DNS server are authentic, or genuine.
Security with DNSSEC
When a home user surfs the web, she or he sends queries to
the Internet by entering URLs in the address line of the brows-
er. A URL is the name of a web site that is easy to remember,
such as www.avm.de/en
. Every query is sent to the DNS serv-
er first. The DNS server resolves the URL into the correspond-
ing IP address. There is one unambiguous IP address for
every URL.
The “DNSv6 Server” area is displayed only if you en-
abled IPv6 support for the FRITZ!Box on the “IPv6” page.
