Does PFSense use a static IP address?

Most non-business internet connections provide service through a dynamic IP address as opposed to a static one. To enable remote devices to locate and access our network we can use a dynamic DNS service that can keep a DNS record updated with our networks current local WAN address. PFsense has such a service that supports a wide variety of DNS services. This guide will use Amazon’s Route 53 but the same principles apply to the other services although the authorisation settings may vary slightly.
