Now assume Host A IP address is 212.149.5.50, Host B IP address is 212.149.105.150, and subnet mask is 255.255.255.0. 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: 212.149.5.0, B's NetID: 212.149.105.0, No, Host A's valid IP range: 212.149.0.1 to 212.149.255.254, Host B's valid IP range: 212.149.0.1 to 212.149.255.254 A's NetID: 212.149.0.0, B's NetID: 212.149.0.0, Yes, Host A's valid IP range: 212.149.0.1 to 212.149.255.254, Host B's valid IP range: 212.149.0.1 to 212.149.255.254 A's NetID: 212.149.5.0, B's NetID: 212.149.105.0, Yes, Host A's valid IP range: 212.149.5.1 to 212.149.5.254, Host B's valid IP range: 212.149.105.1 to 212.149.105.254 A's NetID: 212.149.5.0, B's NetID: 212.149.105.0, No, Host A's valid IP range: 212.149.5.1 to 212.149.5.254, Host B's valid IP range: 212.149.105.1 to 212.149.105.254
