Got to stop using classful addressing terminology... It's only been 16 or so years and you're not referring to: 192.0.0.0/5 Snake-oil salesmen abound in this space. More to the point, any technique used to sculpt pank-rank scores on a systematic basis is likely to result in a countervailing adjustment by search engine operators. http://en.wikipedia.org/wiki/Search_engine_optimization http://en.wikipedia.org/wiki/PageRank Sebastian Wiesinger wrote:
Hello Nanog, I'm looking into a weird request which more and more customers have. They want "different Class C addresses", by which they mean IPs in different /24 subnets. The apparent reason for this is that Google will rank links from different /24 higher then links from the same /24. So it's a SEO thingy. I googled a bit and found pages after pages of FUD and such great things as the "Class C Checker": "This free Class C Checker tool allows you to check if some sites are hosted on the same Class C IP Range." My question is: Is there any proof that Google does differentiate between /24s, or even better is there any proof that this isn't the case? I will not give a customer space from different address blocks just because he read it in a SEO magazine. Perhaps someone from Google itself can answer this question? Also how do you handle such requests? I expect I'm not the only one who gets them. Regards, Sebastian
