What binary value indicates IP version 6 in the IP header's 'Version' field?

The 'Version' field in the IP header is used to indicate the version of the Internet Protocol being utilized. For IPv4, the binary representation is 0100, which corresponds to the decimal value 4. For IPv6, the binary representation is 0110, which signifies the decimal value 6. This differentiation is crucial because it allows networking devices to properly interpret and process packets according to the protocol version in use.

The context of the other options highlights that they represent different binary values that do not correspond to IPv6. For example, 0100 clearly indicates IPv4, while 1000 and 1100 would suggest versions that are not standard and not recognized in the context of the existing IP protocol suite. Therefore, understanding that 0110 specifically denotes IPv6 is key to identifying the correct answer in this scenario.
