, A high school in New York (school A) is using videoconferencing technology to establish
student interactions with another high school (school B) in Russia. The
videoconferencing is conducted between two end devices through the Internet. The
network administrator of school A configures the end device with the IP address
209.165.201.10. The administrator sends a request for the IP address for the end
device in school B and the response is 192.168.25.10. Neither school is using a VPN.
The administrator knows immediately that this IP will not work. Why?
This is a private IP address

A message is sent to all hosts on a remote network. Which type of message is it?
directed broadcast
