Hi All, I have one or two questions about creating an internal and external FQDN. 1. For the external FQDN, can I use a free service such as https://www.changeip.com/ which allows me to choose one of their subdomains for free and map it to an external IP address. 2. Is there many on here that use Pfsense or TinyDNS to resolve their internal FQDN, I assume not everyone uses the Windows server platform. Thanks.
