Today I am very busy. But I can spare a little of my time to write this article. I want to write on a topic that many of you should already know about the IP for difference of class A/B/C. But it may be a little confusing for newbies. Usually IP addresses that we use today consist of 4 parts.
When we say IP with different C class, that means the IP addresses are different in part CCC and illustrated as AAA.BBB.CCC.xxx. For example, 18.104.22.168 and 22.214.171.124; these two IPs have different C class because 23.223.12.xx and 23.223.23.xx are different but the part A and B are the same which is 23.223.xx.xx
When we say IP with different B class, that means the IP addresses are different in part BBB and illustrated as AAA.BBB.xx.xxx. For example, 126.96.36.199 and 188.8.131.52; these two IPs have different B class because 23.223.xx.xx and 23.250.xx.xx are different but the part A is the same as it begins with 23.
Some are confused with the above example 184.108.40.206 and 220.127.116.11. Are these IPs different C class or not? Some may be mistaken as not because the position xxx.xxx.CCC.xxx is the same 15, which is wrong. When you look at IP, you must look at the whole set of number which is 23.223.15.xx is different from 23.250.15.xx is called different C class.
IPs with different A class is the most difficult to find. There are not many service providers that can provide a lot of class A IPs in the order of 100s. Different A class can be noticed at the first set of IPs. For example, 18.104.22.168 and 22.214.171.124 are of different A class, B class and C class with the rules I just explained.
So don’t be confused when buying hosting for private blog network. We want C class but the service provider have different B class (which is better). We are usually mistaken that we want C class, why sell me B class. In fact, different B class IPs will be different C class IPs by default. If you have different A class, then it will be of different B/C class. Is this clear? Comment below if you have any question.
