Both are correct but show different values. Prefix wise they are the same.

:: is one or more zeros.

Thanks.

Khan,

These are both valid addresses. Zeroes have been suppressed. If you look at these addresses in the extended format, they would look like this:

FEC0:0000:0000:000E:0000:0000:0000:0001/64

FEC0:0000:0000:000E:0001:0000:0000:0000/64

Note that the network portion is the same for both (FEC0:0000:0000:000E) and only the host portion is different. I guess the difference is easier to see this way.

Regards
