Blog network/cross-linking - do multiple Class C's help if it's the same nameserver?

    Lots of hosts offer you dozens of IP's spread across multiple Class C's for your VPS/dedicated server.

    But, they would still have the same nameserver.

    So what's the effectiveness here in terms of cross-linking site/blog networks on the same machine? As opposed to if you had those sites each on a different nameserver/class C and were cross-linking across different machines.

    Is there any data or first hand experience people have on this? Or is this a mystery thing that either no one's looked into, or no one is sharing...

    In my opinion it depends on how large the host is and how they set up their nameservers.

    Hostgator gives different nameservers based on the server you're one. ns5820.hostgator.com for example.

    Namecheap gives the same nameserver for every domain they host. ns1.namecheap.com

    Both of those are good in my opinion as long as you Hostgator accounts are on different servers and therefore have different nameservers. Never use your own nameservers unless you can set them up for each domain.

    I'm not sure if you understood me. I'm talking about hosts that give you multiple class C IP addresses on the same VPS/server. Hostgator has it's service like that but it's called seohosting.com. Your nameserver will be the same there.

    I'm saying if it's all your websites on the same VPS/server with multiple class C's, but they must share the same nameserver, how does that compare to if you truly had them on different servers.

    So there's three options:

    1) Normal server - same class C, same nameserver
    2) Multiple Class C server - multiple class C IP's, same nameserver, different class C IP for each domain
    3) Use lots of different servers...far more work, obviously

    If you're cross-linking across sites, obviously option 3 is best, but just how much better might it be than option 2?

    Has anyone who has used option 2 for a blog network/network of cross-linked sites think they suffered substantially for it, or is it not that much worse than 3? Because option 3 would cost you a ton more time.

    One of them problems I have experienced with using the same hosting network with multiple C IP's is that sometimes they migrate networks. For example, with the host nine web hosting provider, if you created a new website every other day, you would get a new IP. The problem is that months down the road they started to migrate the IP's and some of my websites landed on the same IP address.

    1) Definitely deindexed.
    2) Possibly deindexed.
    3) Not likely to be deindexed.

    Multiple class C IP addresses started getting deindexed about 3 years ago. Google knows which company owns the IP blocks, they know that Hostgator owns SEOHosting.com and SEOHosting.com is selling different class C IP's to the same people. The only people who use SEO Hosting are people looking to hide their tracks, i.e. blog networks.

    If you want to truly hide your tracks, you MUST use option 3, not a single doubt in my mind.

    By the way, I built my first blog network 8 years ago. I've been down this path a few times.

    Whatever you do, don't link any of your PBN blogs to another. That would only increase the risk of your money sites and PBN blogs getting penalised or deindexed.
