ProxyMesh supports hostname authentication. This is intended for when you need to use IP address authentication, but you have a dynamic IP address. Instead of constantly going back to the dashboard to update your IP address, you can enter a hostname, which is immediately resolved to an IP address, then re-checked every 15 minutes. If the IP address for the hostname changes, then your authentication gets updated automatically. A common way to update the IP address record for your hostname is to use dynamic DNS, such as Dyn or NoIP.com.
