Dynamic DNS (DDNS)
I saw this at NVIDIA. This had to be configured on the robot.
DDNS is a method of automatically updating a name server in the DNS.
Often in real time, with the active DDNS configuration of its configured hostnames, addresses or other information.
This is so that when you do something like ssh user@robot1, the robot1 needs to be resolved to some actual IP address. Since this IP address can change over time, you can have a DDNS script that automatically updates the DNS lookup table when your IP changes.
