• Additional IPv6 DNS Server – Secondary DNS server.
• Delegated IPv6 Network – (optional) Network available for delegation to LANs. Depending on your provider, this may be required. Prefixes
specified here only take effect if those supplied by the connection are insufficient to configure your LANs.
• Delegated IPv6 Network – Additional network available for delegation to LANs.
Example Configuration:
Out of the box, 6to4 is the simplest mode to enable full end-to-end IPv6 connectivity in an organization if the upstream ISP properly routes packets
to and from the 6to4 unicast relay servers.
• Primary IPv6 DNS Server – (optional) Depending on your provider, this may be required. This only takes effect if the default global DNS
setting on the Network Settings > DNS page is "Automatic".
• Additional IPv6 DNS Server – Secondary DNS server.
• Delegated IPv6 Network – (optional) Network available for delegation to LANs. Depending on your provider, this may be required. Prefixes
specified here only take effect if those supplied by the connection are insufficient to configure your LANs.
• Delegated IPv6 Network – Additional network available for delegation to LANs.
Example Configuration:
The 6in4 tunnel mode utilizes explicit IPv4 tunnel endpoints and encapsulates IPv6 packets using 41 as the specified protocol type in the IP header.
A 6in4 tunnel broker provides a static IPv4 server endpoint, decapsulates packets, and provides routing for both egress and ingress IPv6 packets.
Most tunnel brokers provide a facility to request delegated networks for use through the tunnel.
