Which statement about IPv6 is described in the material?

• A. Addresses are 128-bit and decimal.
• B. Addresses are 32-bit and binary.
• C. Addresses are 256-bit and octal.
• D. Addresses are 64-bit IP addresses and hexadecimal.

Answer: (D)

IPv6 uses 128-bit addresses and writes them in hexadecimal, not decimal or binary. A full address is eight groups of four hex digits, separated by colons, like 2001:0db8:85a3:0000:0000:8a2e:0370:7334. You can shorten by dropping leading zeros within a group and can compress a run of zero groups with a double colon once in the address, giving forms such as 2001:db8:85a3:0:0:8a2e:370:7334 or 2001:db8::8a2e:370:7334. The key idea is that IPv6 expands to 128 bits and uses hexadecimal notation, unlike options that propose 32-bit decimal, 64-bit decimal, or 256-bit octal representations.
