Question

True of False?

Every router has a MAC address and, when a router is moved from one room to the other or from one building to another building, its MAC address never changes.

Every computer, PC or server, is allowed to have one and only one IP address.

Once an IP address is assigned to a device, the IP address never changes when the device is placed in different location.

The default subnet mask of a standard Class B network can be any value between 255.255.0.0 and 255.255.255.0.

To divide a standard Class A network into two subnets, we need a subnet mask of 255.128.0.0.

Explanation / Answer

1) True

MAC address is a hardware based address. So merely moving a router from one building to the other or from one room to the other will not change the MAC address.

2)True

A PC can have only one IP address in a network. A PC is connected to only one network , hence it can have only one IP address. On the contrary, devices like switch, bridgeetc. can have more than one IP address on different hardware interfaces.

3)False

The IP address of a device may change when it connects to a different network in a different place.

4) True The subnet mask may depend on the number of subnets that the class B address is divided into.

5) True
