Can someone explain to me C class IP's for a PBN

It's only a simple question but I am trying to find out which part of the IP address I have to make sure it is different on my PBN sites.

I have a package with ixwebhosting.com which gives me 15 dedicated IP address but each time I add a new domain the IP only goes up one digit (unless some one else has added a site in between)
EG, one domain 123.123.123.01, next domain 123.123.132.02

I have been reading up on this and most people say that the C Class is the bit that needs changing, which means I would need say 123.123.123.01 and say 123.123.124.01 so they third number in the sequence is the one that has changed and is important, is this correct? If this is at the case it's a bummer for me as I will have to wait ages other people add domains and the third number changes, especially waiting for 15 to change.

Yes,the 3rd one.

Stop messing around with the IP-s and get yourself some dozen accounts in different hosting companies that have cheap prices per year. The only thing you need to do is check frequently what other websites are on the same IP that your sites are and if you detect any "bad neighbors" in large quantity such as spam sites, Chinese ones, other PBN-s etc, you tell the company to move your site(s) on another IP. Stop over-complicating stuff and throwing away money on such things because most people say it - think logically with your own brain

Each of the numbers between the dots is called an octet. There are four octets in an IPv4 address. There are multiple ways to subnet blocks of IPs, but a class C has 254 usable addresses. The first 3 octets don't change. The fourth octet would range between .1 - .254

So I only have to worry about the 4 number block changing, not the third? So 123.123.123.001 and 123.123.123.02 would be ok for a PBN?

Damn, I was hoping it as the 4th one.

Makes me wonder why so many people recommended ixwebhosting for PBNs in the first place then, will take ages until that number changes.

If you want to stay safe use only A/B IPS. C class ips will leave a footprint if they are from the same location and are all linking to a site. (only applies to a large network. If you have like 5-10 domains it won't really matter as much)

For a class C, correct.

Class B the 3rd or 4th octet could change.

Class A, the 2nd, 3rd or 4th octet could change.

Gross oversimplification of subnetting.

Ok, luckily I've managed to cancel ixwebhosting.com, can't say anything but good things about them as I did get a good service from them, it just wasn't suitable. So now it's time to crawl through BHW to find a better method. Unfortunately it seems everyone is divided on the subject as to whether separate cheap hosters are better, or if a reseller with different a/b/c ips is better. I'll probably go with the latter just for ease of use, but time for more reading before a decision's made.....

That's why you should use different hosting for each PBN domain.
