Which IPv6 address is valid?
A.
2001:0db8:0000:130F:0000:0000:08GC:140B
B.
2001:0db8:0:130H::87C:140B
C.
2031::130F::9C0:876A:130B
D.
2031:0:130F::9C0:876A:130B
Explanation:
An IPv6 address is represented as eight groups of four hexadecimal digits, each group
representing 16 bits (two octets). The groups are separated by colons (:). An example of an IPv6
address is 2001:0db8:85a3:0000:0000:8a2e:0370:7334. The leading 0’s in a group can be
collapsed using ::, but this can only be done once in an IP address.
Also A and B is true for me…
2001:0db8:0000:130F:0000:0000:08GC:140B = A is ok
2001:0db8:0:130H::87C:140B
2001:0db8:0000:130H:0000:0000:087C:140B = and this is B

Hexadecimal addressing ranges from 0 – F. Therefore A and B are not valid as they contain characters G and H in their addresses.
