IPv6 address prefix length

Specify an IPv6 address including the prefix length for this interface.

Anmerkung: The default prefix length is ​64 bits ("/64")​. If possible do not use IPv6 addresses with longer prefixes, as many IPv6 mechanisms in the device are designed for a maximum length of 64 bits.
A possible address is, for example, "2001:db8::1/64". An interface can have multiple IPv6 addresses:

"Link local addresses" are fixed and not configurable.
