Web browsers will generally add this for you when testing via the above url.
You must carefully weigh the convenience of this facility for users against the security risk created when you enable dynamic DNS updates.
The software utility then periodically checks for a change to the computer's IP address, and when a new IP address is discovered, it updates the Dynamic DNS database to reflect that change.
DNS requires that a name server somewhere on the Internet keep track of 'where you are' (i.e. That is, its database must always be updated to make sure your hostname always corresponds to your current IP address.
If I run ipconfig /registerdns from any of the clients. There is no error any of the event logs (server or local) and the static entry in forward never updates. I noticed on each record that there is an account called Self with special permissions, yet when you drill down there are none set.This synthetic record: Once you set up the Dynamic DNS synthetic record, you must set up a client program on your host or server (the resource behind the gateway) or on the gateway itself that detects IP address changes and uses the generated username and password and communicate the new address to the Google name servers. IPv6 addresses are typically not dynamically assigned.Tip: Directing a wild card (*) to a dynamic resource: While you cannot use a wildcard in a Dynamic DNS record, you can direct a wildcard to your naked domain or a particular subdomain with a CNAME record.If I restart the machine, it still does not update. I hate to have to delete all this suff in forward, because I am not sure which items actually need to be static.The only way it seems I can get the record in forward to timestamp and shows its dynamic is if I actually delete the entry in DNS and then either ipconfig /registerdns or just restart the dhcp service. Plus if I delete it in forward it removes it in reverse which some applicationsare using, then they have issue.
