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 addresses are 128-bit values written in hexadecimal notation. This large size expands the address space dramatically beyond IPv4’s 32-bit addresses, allowing many more devices to be uniquely identified on the network. The hexadecimal form uses digits 0–9 and letters a–f and is typically shown as eight groups of four hex digits separated by colons, for example: 2001:0db8:85a3:0000:0000:8a2e:0370:7334. You can omit leading zeros within a group, and consecutive zero groups can be compressed with a double colon once in an address. The material’s description matches this hex, 128-bit representation. The other statements mix up either the size (not 128 bits) or the numeral system (not decimal, binary, octal, or 64-bit), which is why they don’t describe IPv6 correctly.
