The prefix for the host address 2001:Db8:Bc15:A:12ab::1/64 is 2001:Db8:Bc15:A::/64.
What is the prefix for the host address 2001: DB8:BC15: A:12 ab::1/64?
Answer: the network side of the host address is determined with the prefix length. A/64 indicates the prefix length of the 64 bits of the IPV6 address. that’s why the prefix is 2001: DB8: BC15: A.
Let’s take a look at the method to determine the prefix of the IPV6 address in the following section. That’s why to read or learn it to the very end!
What is a network prefix?
A prefix is the aggregation of the IP address and the IP has two versions IPV4 and IPV6. the V4 has 32 bits while the V6 has 128 bits in a number. With the use of technology, the IPV4 is not enough that’s why the IPV6 is developed. The prefix length finds the accumulation of the number of bits is the accumulation is also determined by it. The prefix finds the number of IP addresses in the specific host part of the address.
Let’s see at the simplified example for the prefix consider the internet as the city and the prefix as the city block while the IP address is the building block of the city. If the city block is present then the building block is also with the IP address and with each IP address of the building the block is itself the prefix.
The prefix of the IPV6 address
IPV4 gas its subnet mask and regard of 255.255.255.0 we can use the prefix length. such as the IPV6 prefix length is:
2001:1111:2222:3333: :/64
Behind the / the numbers used to indicate the prefix number, we can use. And the above example (2001:1111:2222:3333: :/64) shows the prefix of 64 bits and another number behind it is used for the host.
Unlike the IPV4 in the IPV6, we can find the prefix and it works differently rather than find the subnet mask. Let’s see an example:
2001:1234:5678: 1234:5678: ABCD: EF12:1234/64 which is the prefix? And which are the Ip address and the host?
As we know that /64 bits mean the first 64 bits are the prefix. the hexadecimal has 4 bits which mean 2001:1234:5678:1234 is the prefix part of the address. Since the prefix part has 16 hexadecimal characters which means 16 *4 = 64 bits and the rest of the address is the IP address that determines the host.
5678: ABCD: EF12:1234
Now that the Prefix part is determined but the written form of it is not correct. for prefix, an extra zero are present at the end of the prefix, such as
2001:1234:5678: 1234:0000:0000: 0000:0000/64 is the exact prefix length we can also shorten it to the 2001:1234:5678:1234: :/64.
