Hi how is it going? I have been building a network of bloggers for the past month or so and I went to grab the IP's to check to see if they would be good to get links from and I discovered something that I haven't came across in the almost three years I've been doing seo. I put the list which contained about 40 sites in this Bulk Class C IP Checker - http://www.authoritydomains.com/bulk-ip-checker.php - and it listed that 36 were duplicate class C IP's.... Would you get links from duplicate class c IP's? The thing is, the IP addys numerically appear like they are far enough apart, but the tool says they are duplicate IP's.. Can someone shed some light on me as far as Duplicate Class C IP's and linkbuilding utilizing blog networks is concerned?? I built up a list of a couple thousand bloggers, and these duplicate class c IP's have cut that list down to probably 400 or 500.... What to do? I stay away from them correct? Thanks in advance.
