Operating Instructions and Installation Instructions

IPv6: The New Internet Protocol
FRITZ!Box 6820 LTE 57
The home user relies on the authenticity of the IP address re-
turned by the DNS server. Authentic means that the response
is the IP address of the desired website, and not a faked IP
address that leads to a fake website. DNSSEC can ensure that
the returned addresses are authentic.
Support with the FRITZ!Box
The FRITZ!Box supports DNSSEC queries over UDP.
The FRITZ!Box has a DNS proxy. The computers in the home
network use the FRITZ!Box as a DNS server. The FRITZ!Box for-
wards DNSSEC queries from the home network to the Inter-
net. The FRITZ!Box forwards DNSSEC responses from the
Internet to the home network. The DNSSEC information must
be validated on the computer in the home network. For this
DNSSEC must be supported in the operating system.
11.9 IPv6: The New Internet Protocol
IPv6 stands for Internet protocol version 6 and is the succes-
sor to IPv4.
The FRITZ!Box supports the new Internet protocol IPv6, as
long as the connection is over LTE. IPv6 technology is not sup-
ported in the UMTS and GSM mobile networks. Ask whether
your mobile communications provider supports IPv6 in the
LTE network.
If the provider supports IPv6 according to release 8 of the
3GPP standard, the FRITZ!Box receives a single native IPv6
address. If your mobile communications provider supports
IPv6 in accordance with release 10 of the 3GPP standard, the
FRITZ!Box receives a continuous range of native IPv6 address-
es.
