It was suggested that I start my own thread, to make it easy to find the info that I have posted over a few threads, which burst the SEO Hosting bubble. In doing so, it will save a lot of people: time, money and effort.
I won't be covering any new info, just copying my existing posts as quotes and arranging them in a logical order. Although one thread that I contributed to is no longer available, so I'll have to cover the missing info here.
If you want to see some of the original posts, take a look at the following threads (which are still avaiable):
Let's begin...
SEO hosting is sold as the magic bullet for all your SEO issues. The idea is valid, but no one offering SEO Hosting - actually implements what they say (but I'll show you, how to do it yourself).
Lets start off with the basis of the whole SEO hosting sales pitch - Class C IP addresses.
The IP address classes are defined as follows:
Little note for the quote below:
For those who cant make heads or tails out of the above - the key is the moving: 0 - see below:
Below I cover when Classful addressing stopped being used - when they stopped handing out IP addresses based on class. The Important bit is in blue:
I once came across a seo hosting company once that described Class C IP addresses as being defined as the 3rd octet. In the Class quote at the beginning, you?ll see the numbers are grouped and separated by dots. Each groping is called an octet (it?s to do with the binary bits, as it?s 8 bits that are used). Example:
The square brackets used above, are used to make it easier to make out the dots in the example.
The SEO hosting company, claimed right on the front page of their website, that Class C IP addresses were defined by the 3rd octet. Their thinking was as follows:
As I have shown, all the classes are defined in the first octet.
More still to come, so please refrain from posting until I have finished. If you need to know how to do it properly - take a look at the links I provided at the top of this post.

Lets start off with the basis of the whole SEO hosting sales pitch - Class C IP addresses.
The IP address classes are defined as follows:
Little note for the quote below:
The first set of numbers under the class name is: starting IP address, after the "=" is the binary long form.
The second line is the: ending IP address, followed by the binary long form, after the "=".
The third line shows you how the IP addresses in that class are used.
The second line is the: ending IP address, followed by the binary long form, after the "=".
The third line shows you how the IP addresses in that class are used.
The classes are defined as follows:
Class A
0. 0. 0. 0 = 00000000.00000000.00000000.00000000
127.255.255.255 = 01111111.11111111.11111111.11111111
0nnnnnnn.HHHHHHHH.HHHHHHHH.HHHHHHHH
Class B
128. 0. 0. 0 = 10000000.00000000.00000000.00000000
191.255.255.255 = 10111111.11111111.11111111.11111111
10nnnnnn.nnnnnnnn.HHHHHHHH.HHHHHHHH
Class C
192. 0. 0. 0 = 11000000.00000000.00000000.00000000
223.255.255.255 = 11011111.11111111.11111111.11111111
110nnnnn.nnnnnnnn.nnnnnnnn.HHHHHHHH
Class D
224. 0. 0. 0 = 11100000.00000000.00000000.00000000
239.255.255.255 = 11101111.11111111.11111111.11111111
1110XXXX.XXXXXXXX.XXXXXXXX.XXXXXXXX
Class E
240. 0. 0. 0 = 11110000.00000000.00000000.00000000
255.255.255.255 = 11111111.11111111.11111111.11111111
1111XXXX.XXXXXXXX.XXXXXXXX.XXXXXXXX
key:
n indicates a binary slot used for network ID.
H indicates a binary slot used for host ID.
X indicates a binary slot (without specified purpose)
So the {Class C IP addresses} start at 192.0.0.0 and end at 223.255.255.255 with a /24 subnet mask or 255.255.255.0 . Excluding the 192.168 non-routable private address range.
For those who cant make heads or tails out of the above - the key is the moving: 0 - see below:
Class A
0nnnnnnn.HHHHHHHH.HHHHHHHH.HHHHHHHH
Class B
10nnnnnn.nnnnnnnn.HHHHHHHH.HHHHHHHH
Class C
110nnnnn.nnnnnnnn.nnnnnnnn.HHHHHHHH
Class D
1110XXXX.XXXXXXXX.XXXXXXXX.XXXXXXXX
Below I cover when Classful addressing stopped being used - when they stopped handing out IP addresses based on class. The Important bit is in blue:
Don't want to hijack your thread, but I covered the whole "Class" issue pointing out the errors in the statements that were made as well (I do agree it is a somewhat longish thread)..
For those who havn't read the other thread I cover it from post 53 of the thread that the OP links to.
Another post that I made in a different thread, should also help in why SEO hosting is suspect. The following is a copy of my post in that thread (see here for the full thread):
Basically put, in order for SEO hosting to work they way it's sold, you'd have to host as if you had access to servers in different countries across the world. Once you get to that level of separation then we can really discuss SEO hosting - the way the idea is sold, but not implement.
I've been waiting for someone to bring up a little glaring problem with Class C usage. But as no one has brought it up I might as well put this stupid concept to death. Classful address ranges stopped being used as the means of dividing up the pool of IP address in 1994. Good luck trying to get a real class C address range today let alone 10 years ago.
From 1994 VLSM (Variable Length Subnet Masking) become the standard way of giving out IP address ranges. Now that's not to say that those who were given real class C IP address ranges stopped using them or can still allocate them today it's just very unlikely that any hosting company offering SEO hosting will actual have any real class C address ranges with a real /24 subnet mask (aka: 255.255.255.0) Which is why I wanted access to a test account to run ifconfig as that is the only way to tell.
I once came across a seo hosting company once that described Class C IP addresses as being defined as the 3rd octet. In the Class quote at the beginning, you?ll see the numbers are grouped and separated by dots. Each groping is called an octet (it?s to do with the binary bits, as it?s 8 bits that are used). Example:
192. 0. 0. 0 = 11000000.00000000.00000000.00000000
223.255.255.255 = 11011111.11111111.11111111.11111111
[1st octet].[2nd octet].[3rd octet].[4th octet]
The square brackets used above, are used to make it easier to make out the dots in the example.
The SEO hosting company, claimed right on the front page of their website, that Class C IP addresses were defined by the 3rd octet. Their thinking was as follows:
[Class A].[Class B].[Class C].[Class D]
As I have shown, all the classes are defined in the first octet.
