If you have Private Reseller or Global Reseller account, you can request one dedicated IP (free of charge). That IP can be used as "shared" across many websites created via cPanel or WHM. Your websites will use own dedicated shared IP intead of main server IP.

You can request free dedicated IP via Help Center > "Dedicated IP request". In the same ticket, please specify your reseller account: username to WHM and domain name. We'll assign dedicated IP then make it "shared" for newly created websites.

Note: IP changes should be done during weekends. Your website(s) may appear down during DNS propagation. It may take 4-6 hours.
