IPv4-Mask-Length

Defines the number of significant bits of IPv4 addresses that are identical within a 6rd domain. With mask length "0" there are no identical bits. In this case, the entire IPv4 address is used to generate the delegated 6rd prefix.

The provider sets the mask length.

Example: The IPv4 address of the device is "192.168.1.99" (in hexadecimal: "c0a8:163"). In this case, the following are examples of possible combinations:

6rd domain Mask length 6rd prefix
2001:db8::/32 0 2001:db8:c0a8:163::/64
2001:db8:2::/48 16 2001:db8:2:163::/64
2001:db8:2:3300::/56 24 2001:db8:2:3363::/64
SNMP ID:
2.70.1.3.6 
Console path:
Setup > IPv6 > Tunnel > 6rd
Possible values:

0 … 32

Default:
