On a similar issue, I have a debate going on in my company about SEO and links coming from IP blocks allocated from different upstream providers will improve page ranks. (So, if I have block A from provider 1 and block B from provider 2, web sites linking each other on block A & B, the rank will go up) Not just different /24, /24s reassigned from different upstream. I can't find anything to prove or dis-prove this theory. Anyone have a link or info on this issue/myth? I shared this discussion thread and was told it's only discussing different /24, not /24 allocated to different providers. As far as I am concerned, if Google used ARIN swip record or routing entry, it's going to identify us as the end provider so I can't see how who gave us the IP would matter.

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.
