The shortest possible notation of the IPv6 address 2001:0DB8:0000:0001:0000:0000:0000:F00D is 2001:DB8:0:1::F00D. The address is shortened according to the following rules:
* Remove leading zeros.
* Remove the consecutive fields of zeros with double colon (::).
* The double colon (::) can be used only once.
The option 2001:DB8::1::F00D is incorrect because the double colon (::) can be used only once in the process of shortening an IPv6 address.
The option 2001:DB8:0:1:0:0:0:F00D is incorrect because 2001:DB8:0:1:0:0:0:F00D can be further shortened to 2001:DB8:0:1::F00D.
The option 2001:0DB8:0:1::F00D is incorrect because 2001:0DB8:0:1::F00D can be further shortened to 2001:DB8:0:1::F00D.
