- Class C IP addresses

Linking within the same class-c IP can be an indication of common ownership
and as such links may not be counted. If this is true then that is surely
bad news for small web designers and hosting resellers etc who buy domains
from the same company and all domains share the same ip address. Also you
have no idea who else shares that class c address with you!!
For example - Webfusion have the ip range 22.214.171.124 - 126.96.36.199, on
this range they host 115581 sites, so, if I am correct,
115581/255=453.258824, that's about 450 sites per class c address!
I'm personally not seeing a problem here but if there is any basis in the
theory then it could effect a lot of people.

Re: Class C IP addresses
My 2 cents... Given the situation with IPV4 even though
IPV6 is begining to roll out, and the fact that it should
be legitimate to use virtual hosting and IP masquerading
for the maximum of possible 255 unique address which doesn't
take into account broadcast addresses... I can't imagine how
google would pay attention at the class C level.
