The A, B and C Class IP address in web hosting
I have written several articles about multiple IP PBN SEO hosting, and I see there was some confusion still on the internet about understanding what is an IP Address and the different types of IP addresses such as A, B and C Class in hosting.
In this paper, I will go into looking at each type of IP address and references some sites to further check for the accuracy of the difference of each type of IP address class.
I’ve been doing SEO since 2014 and one of the earlier guys who used PBN hosting aka private blog network hosting with unique IP addresses to host my PBN SEO sites. Back then I look at the uniqueness of each IP address when hosting my domains. I wanted unique IP addresses when buying PBN/SEO hosting. Mostly back then for the cheaper prices, we got the Class IPs and that looked like > 220.127.116.11
There are many articles that explain what is an IP address and in relation to answering people who search on the internet for what is my IP address, but in this guide I will talk about the relation to web hosting technology.
What is an IP address?
An IP address stands for internet protocol which is a unique number that will help identify a device or web address. These addresses help transfer data in between devices and help internet users navigate the web to visit a particular web address. This is how the fundamental of the internet works by helping exchange data between different computers, routers and finally to websites that users can access.
Each IP address consists set of numbers ranging from 0 to 255. Example 0.0.0.0 to 255.255.255.255
The IP addresses are mathematically constructed and allocated by the world Internet Assigned Numbers Authority (IANA), a division of the Internet Corporation for Assigned Names and Numbers (ICANN) as per the web data shown.
According to the internet, the ICANN is a non-profit organization that was founded in 1998 in the United States. One more thing about the ICANN is that wherever someone registers a domain on the internet, say for example on https://www.seekahost.app/domain-name-search/ SeekaHost or any registrar pays a fee to ICANN to register the domain.
How many types of IP addresses are there?
Now let’s look at how to identify the A, B and C Class IP Addresses of Your Multiple IP Hosting.
Using Multiple IP hosting and confused about what is an A, B and C Class IP address?
In this short guide, we have presented some data that can help you understand.
We gathered the information after much research and referencing this guide.
We recommend you read the full article to understand in detail, however, the below extraction of Network classes will give you the simplified answer to what are A, B and C Class IP addresses.
Watch > Classes of IP Address: Class A, B, C, D and E – YouTube before reading any further.
What are the types of IP address with example?
Internet addresses are allocated by the InterNIC, the organization that administers the Internet. These IP addresses are divided into classes. The most common of them are classes A, B, and C. Classes D and E exist but aren’t used by end-users. Each of the address classes has a different default subnet mask.
The different types of IP address
You can identify the class of an IP address by looking at its first octet. Following are the ranges of Class A, B, and C Internet addresses, each with an example address:
- Class A networks use a default subnet mask of 255.0.0.0 and have 0-127 as their first octet. The address 10.52.36.11 is a class A address. Its first octet is 10, which is between 1 and 126, inclusive.
- Class B networks use a default subnet mask of 255.255.0.0 and have 128-191 as their first octet. The address 172.16.52.63 is a class B address. Its first octet is 172, which is between 128 and 191, inclusive.
- Class C networks use a default subnet mask of 255.255.255.0 and have 192-223 as their first octet. The address 192.168.123.132 is a class C address. Its first octet is 192, which is between 192 and 223, inclusive.

Going further, I can explain about A Class IP address:
See the > 18.104.22.168. It consists of four parts called: Class A, B, C, D. In this address, figure 74 is called Class A; 86 is class B; 246 is class C, and 210 is class D.” as per web data. However, such IP then should be called as different class multiple IP hosting.
If selling unique A Class IP hosting, what’s needed is ex: 22.214.171.124 and 126.96.36.199 and both Ip’s is A-Class because 1st Oct is different 104, and another one is 78.
There is a big demand for unique C Class IP hosting on the web as per Google data and the right C Class IP address for a hosting account should be > 188.8.131.52
