What Is Indicated By A Successful Ping To The::1 Ipv6 Address?
It is indicated as a TCP/IP stack is correctly get installed in it. Now, let us discuss the::1 IP v6 address in detail. Before we discuss the IPv6 addresses first we need to know why IPv6 has been introducing.
When the version of IPv4 was first introduced, they normally have created nearly billions of IP addresses for all the users. Even though we have a lot of the IP addresses that were created, due to the rapid increase in the usage of electronic devices, the Ipv4 address is run out of stock.
This has lead to the introduction of the IPV6 addresses. Besides the IP version 6 addresses, it brought a lot of improvement when coming to traffic. Now, let us know how actually the IPV6 address looks like?. The Ipv4 is 32 bit in length The structure of the IPv4 contains four sections., which we call the octets, these are get separated by the dots. Each part of the Ipv4 address can contain any number between o to 225.
The IPv6 address is 128 bits long when we compared it with the Ipv4 address. This IPv6 address has a very massive address space than the Ipv4 address. The structure of the IP version 6 has normally eight sections. Each part of this Ipv6 version is called the hextets. The below figure 1.1 represents the structure of the Ip version 6. These eight parts are separated by the colons (:).
The main thing we need to notice in the IPv6 address is that it has letters and numbers in it. The characters of the Ip v6 version can be from 0 to 9 hexadecimal forms. Now, let us know the working of the IP version 6 address in detail.
In Ip v6 version, each of the hexadecimal characters is made up of the four binary bits in it. These bits can be of either 0 or 1. The Ip v6 will double each column from the right to the left. If we see 1 in the IP v6 address, it will toggle the column on, similarly, if we see 0 in the IP v6 address then it will toggle the column off.
Let us understand clearly from figure 1.1 given below, When we see the figure, the first number of the Ip v6 address is 2. Here we may get a doubt how can we represent the number 2 in the binary forms?. Simply, we all know that the binary number of 2 is 0010. Here the number 2 simply stores the binary digit of it. In the same way, it works with the other numbers that follow.
And when we see the characters in the Ip v6 addresses. This character can be from 0 to 9 or it can be from A to F. In the figure, we have the character as D. The D represents 15 when we see it in the hexadecimal form. So here the character D can store the value of up to the 15 numbers in it. This is the way how Ip version 6 works.
