I'm using hostgator reseller panel with limit to the number of dedicated IPs. I want to use dedicated IP for each account under control panel. Unfortunately hostgator restricts me with an upsell of SSL+IP for 50$. Which i think a bit costly and packed with unnecessary SSL package which i don't want to use. So is it possible to get dedicated IPs from another hosting service or host keeping the files hosted on different server ? or we're restricted to use dedicated IPs from the same host ?So to frame question in this situation, is it possible to buy IP address from 3rd parties or anyone other than your host ?
Dedicated IP address from 3rd Party Services
web hosting;ip address
Is it possible to buy IP address from 3rd parties or anyone other than your host ?No - upstream hosts will not route to an IP address which does not belong to your host's IP address assignment.So is it possible to get dedicated IPs from another hosting service or  host keeping the files hosted on different server ?Sure, but in that case (unless there is some compelling reason to use a reverse proxy on another network) it makes more sense to simply move your hosting.
