Which of these IPv6 addresses is the same as FF00::1?FF00:1:1:1:1:1:1:1FF00:0:0:0:0:0:0:1FF00::0.0.::0:0FF00:0.0.0.0.0.0.1

To determine which of the given IPv6 addresses is the same as FF00::1, we need to interpret and expand each candidate IPv6 address and see if it is equivalent to FF00::1.

1. **Expand ** FF00::1:

   • The notation :: indicates that one or more groups of zero values have been omitted. In this case, FF00::1 expands to: $FF00:0:0:0:0:0:0:1$

2. Evaluate each candidate:

   • Candidate 1: FF00:1:1:1:1:1:1:1

     • This does not match because it contains additional non-zero segments.

   • Candidate 2: FF00:0:0:0:0:0:0:1

     • This expands to the same value as FF00::1.

   • Candidate 3: FF00::0.0.::0:0

     • This notation is invalid; the :: can only appear once and cannot be followed by a dot notation in this context.

   • Candidate 4: FF00:0.0.0.0.0.0.1

     • This also is incorrectly formatted for an IPv6 address and does not resolve to the valid structure of IPv6.

3. Conclusion: Based on the analysis, the only IPv6 address equivalent to FF00::1 is:

Final Answer

FF00:0:0:0:0:0:0:1
