Just like with any server on the internet, with Etho Protocol nodes it's expected your public IP address will not change. Renting a VPS server or physical server with statically assigned public IP addresses is highly recommended. Users who want to run a node from home should be aware that each time your IP address changes, you will need to re-setup your server. Your Etho Protocol nodes will use a fairly large amount of data; if you're running them from home, make sure your ISP will not suspend you for this reason.
