Which statements are TRUE regarding Internet Protocol version 6 (IPv6) addresses? (Choose three.)
A.
An IPv6 address is divided into eight 16-bit groups.
B.
A double colon (::) can only be used once in a single IPv6 address.
C.
IPv6 addresses are 196 bits in length.
D.
Leading zeros cannot be omitted in an IPv6 address.
E.
Groups with a value of 0 can be represented with a single 0 in IPv6 address.
Explanation:
IPv6 addresses are divided into eight 16-bit groups, a double colon (::) can only be used once in an IPv6
address, and groups with a value of 0 can be represented with a single 0 in an IPv6 address.
The following statements are also true regarding IPv6 address:
IPv6 addresses are 128 bits in length.
Eight 16-bit groups are divided by a colon (:).
Multiple consecutive groups of 16-bit 0s can be represented with double colon (::) ( only once)
Double colons (::) represent only 0s.
Leading zeros can be omitted in an IPv6 address.
The option stating that IPv6 addresses are 196 bits in length is incorrect. IPv6 addresses are 128 bits in length.
The option stating that leading zeros cannot be omitted in an IPv6 address is incorrect. Leading zeros can be
omitted in an IPv6 address.
