These IPs are all in the same A class, all in the same B class, and almost all in the same C class.

In total you got IPs from 2 different C classes (66.199.243.xx and 66.199.226.xx).

If you were promised C class hosting, you got scammed.

The third number is the IP is the C Class (Class C).

You have THREE Class C's in that list.

243, 226 and 231.

only 3 are c class no more then? you are sure?

All of them are class C IP addresses. We are talking about the range of class C's used.

All your class C IP addresses are from the same range

66.199.226.*
66.199.231.*
66.199.243.*

This is only a problem if you asked to have a larger range of different Class C's.

It all depends on what you are going to use them for.

you mean to say C class ips Start from 66. not 192.0.1.1 to 223.255.254.254

Those are all class A IP addresses, but that means absolutely nothing.

Class A = 0.0.0.0 - 127.255.255.255
Class B = 128.0.0.0 - 191.255.255.255
Class C = 192.0.0.0 - 223.255.255.255

The term "class C" is often misused to refer to a block of IP addresses where the first three sections (octets) are the same. Technically, that would be a /24 block, not a class C block.

What you want are IP addresses that are on separate /24 blocks, but you didn't even get that.

i just talk with Seo compnay who giveing me these ips and thy said All Are C class ips not A Class.
so how me proof them these are Class A not Class C?

Here is how IPs are classified: (The IPS in question are all 'A' class)

• Class A IP address ranges are for large networks with many devices (supports 16 million hosts on each of 126 networks). The first octet starts from 1 to 126.
• Class B IP address ranges are for medium-sized networks (supports 65,000 hosts on each of 16,000 networks). The first octet starts from 128 to 191.
• Class C IP address ranges are for small networks (supports 254 hosts on each of 2 million networks ). The first octet starts from 192 to 223.
• Class D IP address ranges are multicast addresses. The first octet starts with 224.
• Class E IP address with the first octet of 225 is used for experimental purposes only.
• The IP address 127.0.0.1 is used as the loopback address. This means that it is used by the host computer to send a message back to itself. It is commonly used for troubleshooting and network testing.

Here is how IPs are classified: (The IPs in question are all 'A' class)

• Class A IP address : The first octet starts from 1 to 126.
• Class B IP address : The first octet starts from 128 to 191.
• Class C IP address : The first octet starts from 192 to 223.
• Class D IP address : The first octet starts with 224.
• Class E IP address with the first octet of 225 is used for experimental purposes only.
• The IP address 127.0.0.1 is used as the loopback address. It is commonly used for troubleshooting and network testing.

Thy said proof us these are not C Class ips then we give you refund otherwise not

[DELETED]

i am very am confused some saying these are A Class and Some Saying These are C Class no one Experts know These are A or C?

There's a lot of confusion and some misunderstanding in this thread, so time for an Internet history lesson......

I'll try to keep things as non-technical as possible.

Originally when the IP addressing scheme was devised, it was broken into three different classes, A, B & C

With a Class A network, you could assign 16,777,216 individual IP addresses within each class A network (of which there were only 128).

Class A network ranges were assigned to big companies like IBM.

Class B had more networks (16,384) and each of these Class B networks had 65,536 IP addresses.

Class C had (2,097,152) class C networks with each network having 256 IP addresses.

This was all well and good in the early days of the Internet and companies that needed more IP addresses than a Class C provided, could quite easily get a class B network range.

The problem is that was a very wasteful practice, because if a company only used a small fraction of their total IP addresses in their allocated network range, it meant they weren't available for anyone else to use.

With the explosion of the growth of the Internet, there was a desperate need for more IP addresses.

In 1993, Classless Inter-Domain Routing (CIDR) was introduced to alleviate the issue of IP address shortage.

Simply put CIDR allowed the old Class A,B,C network ranges to be split into much smaller chunks so that more IP addresses were available for use.

These days, it doesn't really make much sense to talk about Class A,B or C address ranges as they don't really exist anymore.

So in answer to the OP's question, the IP addresses you were given are within the original Class A address range.

The most important question is how many different networks those addresses belong to and that entirely depends on how those address ranges are split up.

tim is right

If oyu need different C class IP addresses, you need to use SEO services which are provided by some companies - seohosting, aseohosting, etc.

Problem Solved get 200 Unique cc las ips from new host

Thans All of you

If you are planing to build a network of sites:

1. Never interlink them (I know you might be tempted)
2. There is NO good reason not to chose 4-5 different hosts, so you name servers are different as well (DNS)
3. I would even go with different who is

Then you are can worry less about them being spotted as a group if that is you worry.

And I see that you are selling link services - then dont use google analytics or any other google services.

Good Luck
