What are B or C level IP addresses, I see some hosts advertising these as better for SEO?

Worth it or not?
My understanding is, this comes more into the case when google sees multiple sites with the same content. They check to see if they are within the same class c address block to see if they may be the same publisher. All Class B and Class C mean is how big a block of addresses one subnet is.

Class B addresses were initially given to respected, or important organizations such as universities, etc. But there isn't anything that would make an ip address of a B Class better for SEO, as far as I know. Classless addressing is what's really being used now, and I see no real benefits of having a B address now.

We actually had to go through a pretty hefty process at my corporation to prove we needed a class C address. Most businesses just need 1 or 2 anymore.
