Domains and IP's
 

How many domains do you have on an IP? What is the recomended number? I have a few unused domains and I was wandering if I should get new hosting or can I add them to my existing without problems.

Any good advice is much appreciated. |thumb

There are over 900 on one of the dating programs i'm using.

I've always thought that is a bad thing so would be interesting to see if anyone knows.

The common wisdom among the SEO world is that it's best to have all your domains on separate IPs, even spread out over different blocks. I'm not all that convinced that's true, but I do it anyway, just to cover all the bases.

If you're not really looking for SE traffic from whatever your doing with the domain, then it really doesn't matter.

I pretty much do what spacemanspiff does. I try to keep my domains on seperate IPs and I have about 4 different hosting accounts with different providers containing all my domains. This gives me some different c-class Ip blocks which may not really help all that much. But I feel better linking my sites together using multiple hosts instead of just one.

OK, so separate domains on separate IPs.

Any recommended hosting besides colo-cation and Webair?

If you're going to use it mainly for freesites/hubs/tgp'ing, Dreamhost may be a good one for your to look at. Lots of bandwidth and space. If you are going to be doing database stuff on it, I'd probably look at some other options as I have noticed some speed issues with my db stuff.

My first two hosts were Protgp and Cyberwurx. I'm still with them both.

This is my guess - if your sites are all of good quality and have unique content it shouldn't matter.

If you are interlinking all your sites just to manipulate PR and they are close to spam then you would want to spread them all around. I'm think the SEO servers are not as good as random virtual accounts spread around the globe.

Google could analyze IP allocation from ARIN, RIPE, etc. If all your IPs are with one data center (even if they are on different /24s) it would look different from a data mining perspective. They could also look at name server diversity, registry information (are all your domains registered at the same company) domain keys, server headers, and who knows what else. I highly doubt they do all that now, but as computing power gets cheaper and more powerful they will probably start adding that type of data to fight spam.

The way I see it is you can either spend your time making quality sites or spend your time making shit and trying to stay one step ahead.

i have to think back, i think a little bird told me to have 2 of the same niches a host if they are on an different ip..i think:D

national net is a good host i've heard.
