Hello, Student

I am going to clear everything related to your question, Please do not forget to hit that like or thumbs-up button, it really motivates me.

Q) Does the MAC address change or is it associated with a specific network interface?

Answer: - MAC address does not chage,is it associated with a specific network interface or it is assigned by manufacturer.

Explanation:- MAC, the full form of MAC is "Media access control" , a MAC address is assigned to device's network adapter when it is manufactured by company.

And Yes It is possible or not hard to spoof MAC address but it is illegel.

Q Part (ii) ) Is there a possibility where two hosts can have the same MAC address or is it globally unique?

Answer: - Basically MAC address is globally unique but as I said about MAC spoof due to this there a possibility where two hosts can have the same MAC address.

Explanation: - For devices communication, the MAC address which is used by device must be unique.

And if two hosts can have the same MAC address on same LAN than their is a big problem.

Q Part (iii) ) What about IP addresses, can a host have one set/unique IP address or does it change?

Answer : -IP addresses keep changing.

Explanation : - If a device have static IP address assigned by network provider than it will not change, will be unique.

But ,most of the devices do not have static IP address, they have dynamic IP addresses, which are assigned by the network and they change over time.

Giving a static IP to every ISP user would have been very costly to company.
