| ROS can be used across a network, with different nodes running on different computers. One computer should be designated as the "server" computer, which runs the rosmaster server (this program, along with a few others, is started up when you run `roscore`). It makes little difference as to which computer runs `roscore`, as the server is not a CPU-intensive task. For convenience, we always set the sub to be our rosmaster server. | ROS can be used across a network, with different nodes running on different computers.

| ROS relies heavily on DNS resolution to map computer hostnames to ip addresses. Normally our router does the DNS resolution, therefore minimal configuration is necessary for network setup. | ROS relies heavily on DNS resolution to map computer hostnames to ip addresses.
