I checked lot of ip address checker..All tools should the answer -- your ip address are spam blocklist...what can i do..could affect search ranking pages and could i do seo or not?
did you use your IP for spamming? which ip address you are talking about? your ISP Ip address or your hosting IP address? in any case, just change the IP either signing up with a different ISP of a different host which should take care of the problem.
