The domain name system (DNS) translates a URL like www.yahoo.com to an IP address like 22.214.171.124.
Dynamic DNS (DDNS) allows the router with the public IP address to be reached from the internet via a URL even if its IP address is dynamically changing.

Hostname: Specifies the hostname e.g. y0033.no-ip.biz.

URL: Sets the URL of the source of the IP address information e.g. http://checkip.dyndns.com/.
