As far as I know, you'd be restricted to a handful of whitelisted IPs/users. That's normal for shared hosting. You'd need a VPS or a dedicated server to run wide-open. What are you planning to do that can't be done with an API brokering access for you?
Yes as free user there is still Option of "% wildcard" But I am not able to use that , if this works I'll surely go for PremiumPremium hosting does indeed allow remote connection, I think you can set it to all rather then one IP by using the wildcard setting, which would be setting it to allow "%".
I'll see if I can get that confirmed by someone that actually works with the premium side of things.
Actually I am Developing Vb.net app for my college So anyone Using that app from anywhere, can be able to Retrieve some / all data from that database
in Short want to Use This as a OPEN Cloud database
