Understanding the IPv6 Default Route: ::/0 and Its Significance

What network prefix and prefix-length combination is used to create a default static route that will match any IPv6 destination?a, :/128b, FFFF:/128c, ::1/64d, ::/0

The correct answer is d, ::/0.

In IPv6, the “::/0” prefix is used as the network prefix and prefix-length combination for a default static route. This combination means that any IPv6 destination address, regardless of its value, will match this route.

The “::/0” notation represents the “default route” or “default gateway” in IPv6. The “::” part represents the unspecified or any IPv6 address, while the “/0” denotes the prefix length of 0, meaning that all bits in the destination address are matched. As a result, this route will be used if no more-specific routes exist for a given destination.

Using this default static route, any packet with an unknown destination IPv6 address will be forwarded to the next-hop router or gateway specified in this route for further routing decisions.
