I would like to know some better positive answer on c- class ips... Why we can't get more links from same C-class ips? what is the disadvantages of it? How can a same C class ip affect a site to rank? I need help in this...
Links from the same C Class IP address are generally hosted by the same ISP, so where significant numbers of website backlinks come from same C Class IP address or same website, such links will be discounted altogether or subject to significant link devaluation such that they may only achieve the equivalent value of just one backlink from the source. Consequently, having many backlinks from the same C Class IP range will offer little Google ranking benefit and PR improvement and may red-flag an attempt to spam the search engine causing Google ranking problems.
