[Android Central Question]

I am not much of a technical person, but I need a VPN to be secure on public Wi-Fi as I use my Laptop mostly in library or cafe. Can anybody recommend me any good VPN service that offers both?

I have shortlisted Ivacy VPN and ExpressVPN. Kindly suggest which one would work best?

I could recommend NordVPN. I'm using it and it works quickly and securely, at least on my end. It seems that they offer dedicated IP's too. Heard that Express is pretty good too, but haven't tried it.

You can't have a static (fixed, dedicated - it's called static) IP address if you're using a public WiFi connection - the IP address is the public WiFi's address.

If the VPN can give you one of their IP addresses as your static address, you'd have to be able to forward that through the VPN app - and I don't know of any VPN app for Android that can do that. One of the purposes of using a VPN is so that no one can get to your phone. If you set it up with a static IP, anyone connecting to that IP address gets to your phone, defeating the whole purpose of using a VPN.

If you want to run a website, I suggest that you buy hosting from a normal hosting company. (Or if you're looking to transfer files with someone and you need the IP address for that, any app you run that does file transfer tells you your current IP address [that's an internal address, not an eternal address, since you're on a router], and the person can connect to that IP address. But that opens your phone up to anyone who overhears you tell them the address.)

You're trying to do two opposing things here. Maybe you should register an account here so you can keep the conversation in this thread - and explain exactly what it is you're trying to do with that static IP address. That may not be what you actually need.
