Now assume Host A IP address is 20.5.5.50, Host B IP address is 20.105.105.150, and subnet mask is 255.255.0.0. Again this may not be a standard Network class (class A, B or C), but you draw your conclusion based on subnet mask definition. What are the Network IDs for Host A and B? Are they in the same LAN? What is the valid IP range for Host A's network? What is the valid IP range for Host B's network? A's NetID: 20.5.0.0, B's NetID: 20.105.0.0, No, Host A's valid IP range: 20.5.0.1 to 20.5.255.254, Host B's valid IP range: 20.105.0.1 to 20.105.255.254 A's NetID: 20.5.0.0, B's NetID: 20.105.0.0, Yes, Host A's valid IP range: 20.5.0.1 to 20.5.255.254, Host B's valid IP range: 20.105.0.1 to 20.105.255.254 A's NetID: 20.0.0.0, B's NetID: 20.0.0.0, Yes, Host A's valid IP range: 20.0.0.1 to 20.255.255.254, Host B's valid IP range: 20.0.0.1 to 20.255.255.254 A's NetID: 20.5.5.0, B's NetID: 20.105.105.0, No, Host A's valid IP range: 20.0.0.1 to 20.255.255.254, Host B's valid IP range: 20.0.0.1 to 20.255.255.254
