Have someone experience with seohosting.com?

I know that its a hostgator.com company, and generally i had good experience with hostgator.

But im interested too if it works for seo purposes. Isnt it possible that Google checks that the different IPs are all from hostgator? And in that case when every IP is from the same hoster wouldnt it be bad for google?

Let me hear you opinion,

Greetings
