VPN can work with dynamic IP but not without public IP otherwise a connection to public Internet just doesn't work.

The general consensus (which I agree with having set up many VPNs over the years) is that for reliable site to site VPN, one end must be a static IP address. For a remote access VPN (on demand, not full time, not site to site) a dynamic IP address at both ends can work well with a dynamic DNS service (e.g. noip.com).

A VPN gateway requires a public IP address for its configuration. A public IP address is used as the external connection point of the VPN. VPN gateway supports standard and basic SKU public IP addresses depending on the SKU of the VPN gateway. Public IP prefixes aren't supported.

If you are a business and need better DNS support or compatibility with VoIP, then you need a static IP address. However, if you are using the internet for personal reasons, you don't need a static IP address, and dynamic will be better.

The reputation of your IP can be affected by the actions of others using the same address. This is where a dedicated IP comes in handy – and they're offered by a lot of today's best VPNs. They ensure that you have a unique IP and allow you to browse the internet untainted by the actions of your fellow VPN users.

Can I request a static public IP address for my VPN gateway? Standard SKU public IP address resources use a static allocation method. Going forward, you must use a Standard SKU public IP address when you create a new VPN gateway. This requirement applies to all gateway SKUs except the Basic SKU.

There can only be one device (or host) using a given IP address at a given time. If one device is using a VPN, then the underlying IP address that is being used will be the same for both devices, so the two devices cannot both have the same IP address.

A VPN replaces your actual IP address to make it look like you've connected to the internet from a different location: the physical location of the VPN server, rather than your real location. This is just one reason why so many people use VPNs.

Access Server requires a static IP address. If you don't have one assigned to your server, clients may connect to your server's dynamic IP address, but when it changes, no longer connect.

If you only need Internet access and don't require outside users the ability to access your internal systems then Dynamic IP may fulfill your needs. However, if others do require outside access to your systems internally hosted (i.e. web, email, FTP or VPN services) then you will need a Static IP.

Static IP addresses normally matter more when external devices or websites need to remember your IP address. One example is VPN or other remote access solutions that trust (whitelists) certain IPs for security purposes.

IP Address Terminology

Static means the IP address never changes as long as you stay with the same provider or same server. Dynamic means the IP address can change from time-to-time. Public means the IP address can be reached via the Internet from any computer in the world.

Using a dedicated static IP address is considered best practice when enabling remote access for the workforce via VPN (Virtual Private Network).

When you connect to your VPN, your tunnel interface is assigned an IP by that remote DHCP server. So you're technically routing from the VPN server to your remote devices. You're probably connecting to your servers via their DNS names or something, which is resolved by your DNS servers locally.

You can't be tracked using a VPN because it encrypts your data. As a result, your ISP or bad actors can't get any information out of your traffic. They only see the VPN server's IP address (e.g. if you're connected to a US server, the US IP address is visible), while your real IP and online activities stay hidden.
