Same IP address but different classes

[nkurma]

Hello masters! Forgive me if this question has been asked already. However, I have not seen it yet. I know that it is advised to get links from domains residing on different IP addresses. I also know that as long as links from different domain they have some weight

Any way, my question is: Which one is considered ok(effective)and SEO friendly?

a)when links are from the same IP address with different "C class";
or
b)when links are from the same IP address with different "D class";

I heard that G tolerates liks from the same IP but how about the effect of those links.

Is there any way that a person can control these two classes (I mean to change them)?

Thank you in advance!

Matt Cutts stated in November that multiple domains on one IP are treated the same as links on several IPs. Here is the quote:

Links to virtually hosted domains are treated the same as links to domains on dedicated IP addresses.

What's important is how you interlink your sites regardless of what IP they live on.

Thank you freelistfool,
I did not know that. I feel quite relieved after reading your post. You said quote "important is how you interlink", May i ask if you know or have something to read where I could learn more about proper interlinking? That would be a great help!

Cheers man!

If you want to know what not to do just search this forum for all the posts on people being penalized by google.

Doing it right really depends on your sites. I try to only interlink my sites where they are actually related. That means on some sites there are only a few links going to the other sites. But on others it is tens of thousands of links. For example, I have 3 sites that are related by one factor (factor X), however, are on different themes. These sites are heavily interlinked by factor X. No issues so far...but I'm watching them carefully.

But that isn't saying anything at all about virtually hosted sites *within* the same IP/C-class linking to each other.

Here's a larger snippet of the quote. You'll see that it differentiates between one IP address or multiple IP addresses. Then makes the leap that multiple web sites on a virtual server will be on one IP address.

I hear that there was recently a discussion on a NANOG (North American Network Operators Group) email list about virtual hosting vs. dedicated IP addresses. They were commenting on the misconception that having multiple sites hosted on the same IP address will in some way affect the PageRanks of those sites. There is no PageRank difference whatsoever between these two cases (virtual hosting vs. a dedicated IP).

Links to virtually hosted domains are treated the same as links to domains on dedicated IP addresses.

Now you can parse the quote to say that he's only talking about PageRank and not all the stuff that makes up the Google SERPS soup. ;).

Thank you folks for your valuable comments. My undertanding has improved with the help of your comments. I see better now the differences and effect.
