Different C Class IP Addresses

[Crazzy]

Do you offer different class C IP addresses for dedicated IPs? More accurately, when I buy, for example, 10 dedicated IPs, can you guarantee that all 10 would have different C class?

It is only important to have different C classes amongst your dedicated IPs if you are linking between sites. What this will do is give you additional credibility with Google because you won't be labeled as a link farm.

If you don't mind, can you please explain what is a C class in an IP address. I know there are 4 triplets of numbers: xxx.xxx.xxx.xxx

An IP belonging to the range 192.0.1.1 to 223.255.254.254 Class C IP address.

How would having the same C class among your IPs make Google think you are a link farm? I thought a link farm was just a site full of garble links? Could you explain the difference or what a true link farm is? Thanks in advance.

I know that for VPS they can set up the IPs where they are in separate Class C networks as they configured mine that way.

Just a heads up, if you use 1and1 for your domain registrations you will need your nameserver IP addresses on separate Class C networks. Otherwise if the IPs are on the same Class C network 1and1 complains that the nameserver is invalid for your server and won't let you use your server's nameservers with their domains.

Well, link farm is considered a bunch of sites that are heavily inter-linked. For example, you have 100 sites and each one is linking to other 99. That is a linkfarm. In addition, situation can be worse if all of those sites are on the same IP (AAA.BBB.CCC.DDD) or IPs that have the same C block. Third triplet (CCC) represents C block of IP. Usually, if your sites belong to different C block IP Google is much more lenient and gives credibility to exchanged links.

This may sound a little confusion.

For example, these are all IPs with different C blocks:
123.123.123.123
123.123.124.123
123.123.234.211
It's even better if you have different A or B blocks:
12.123.123.123

Here is an online checker tool, just enter your domain names to see whether they have the same C block in IP:
