I recently had to change to a new server and noticed that while I wanted to send an email to my @sbcglobal.net email address, it responded back that my IP range has been blocked. Will this have negative effects on search engines when I switch my site over to this new IP? Or does email IP have nothing to do with this.
Hard to say.. Your current host may be blacklisted by Google if it violated the guidelines before.. I would suggest you to create a Google Webmaster Account and monitor your site for abnormal activities.
Since you mentioned email, that may be due to the fact that your IP is on some form of a RBL list - check if your IP is listed as a spam IP.
tell please me how to change my ip in internet, just not to create a new topic, ask here... it's connected witch proxy or not?
