Question

An IPv6 address is 128 bits long and is represented in eight 16-bit hexadecimal segments. An example of an IPv6 address is as follows:

Options:

2001:0db8:85a3:0000:0000:8a2e:0370:7334
ABCD:1234:5678:90AB:CDEF:9876:5432:1001
192.168.1.1
FE80::1

Answer 1

The IPv6 addresses from the options provided are 2001:0db8:85a3:0000:0000:8a2e:0370:7334, ABCD:1234:5678:90AB:CDEF:9876:5432:1001, and FE80::1, while 192.168.1.1 is an IPv4 address.

Step-by-step explanation:

The student's question relates to the format and representation of IPv6 addresses. An IPv6 address is indeed 128 bits long and is typically represented as eight 16-bit hexadecimal segments. Among the provided options, 2001:0db8:85a3:0000:0000:8a2e:0370:7334 and ABCD:1234:5678:90AB:CDEF:9876:5432:1001 are valid examples of IPv6 addresses.

The option 192.168.1.1 represents an IPv4 address, which is a different format, being only 32 bits in length and divided into four 8-bit decimal segments. Lastly, FE80::1 is another example of an IPv6 address, which uses the double colon (::) as shorthand to represent consecutive sections of zeros, a common method to abbreviate IPv6 addresses.
