I have been compressing IPv6 addresses but for some reason I can't compress this one:
2b06:0000:0000:1f2b:d77f:0000:0000:89ce
This is what I compressed it too: 2b06::1f2b:d77f::89ce
But this is not working, and I wonder, why.
This is the correct way to do it: 2b06::1f2b:d77f:0:0:89ce
You can't have :: more than once in one address.
This 2b06::1f2b:d77f::89ce would be ambiguous, as it could expand to
2b06:0000:1f2b:d77f:0000:0000:0000:89ce,
2b06:0000:0000:1f2b:d77f:0000:0000:89ce, or
2b06:0000:0000:0000:1f2b:d77f:0000:89ce.
