Sophos XG: Introduce enhanced DDNS support on firmware version 18


Dynamic DNS is a method of mapping domain names to high-frequency IP addresses

Monitor the change of IP address at the host and contact the DNS system whenever the host’s IP address (provided by the ISP by dynamic method) changes and then updates the information into the DNS database about that address change. This way, even though the server is constantly changing its address, the domain name is still pointed to the new IP address by the DNS server system
