IPv6 is a protocol used for identifying and locating devices on a network. It uses a 128-bit address format, which provides a much larger address space compared to the 32-bit address format used in IPv4. The correct IPv6 address notation is determined by the rules set forth in the standard.
A. 2001:0DB8::/128 This notation is used to represent a single address with a prefix length of 128 bits. The first 64 bits are the global routing prefix, while the remaining 64 bits represent the interface ID. In this case, the global routing prefix is 2001:0DB8::, and the interface ID is all zeros.
B. 2001:0DB8:0:: This notation represents a single address with a prefix length of 64 bits. The first 64 bits are the global routing prefix, and the remaining bits are set to zero. In this case, the global routing prefix is 2001:0DB8:0::.
C. 2001:0DB8::1:1:1:1:1 This notation represents a single address with a prefix length of 128 bits. The first 64 bits are the global routing prefix, while the remaining 64 bits represent the interface ID. In this case, the global routing prefix is 2001:0DB8::, and the interface ID is 1:1:1:1:1.
D. 2001:0DB8:130F:0000:0000:7000:0000:140B This notation represents a single address with a prefix length of 128 bits. The address is represented in eight 16-bit blocks separated by colons. Each block can be represented in hexadecimal notation, and leading zeros can be omitted. In this case, the address can be represented as 2001:0DB8:130F::7000:0:140B.
In summary, the correct IPv6 address notation depends on the specific requirements of the address and can be represented using a variety of formats. It is essential to understand the notation rules to ensure correct configuration and operation of network devices.
