No, MAC Addresses are fixed per network interface card or NIC. The MAC address is the Media Access Control address and is the hardware address of the network device to which your IP address, e.g. 192.168.1.3 is assigned.
You can identify the vendor of your network card from its MAC address, e.g. all Intel NIC cards may begin with 00-15.

How do bridges and switches dynamically create their table?
Bridges and switches learn and filter MAC addressses into memory over time thereby creating a table of Mac addresses. Bridges build a memory table of MAC addresses they get from segments. Switches build tables based on switch port numbers to MAC addresses instead of segment numbers.
Are there any advantages and disadvantages using the assignment of ip addresses automatically?
Advantages: A company can purchase fewer IP addresses since each machine will not be statically assigned a fixed address but dynamically assigned an address when it accesses the Internet. Disadvantages: The software is more elaborate; what if 100 IP addresses are purchased and the 101st user tries to access the Internet?
What happens to the MAC address when you move a computer to another network?
The MAC address is a unique identifier for a networking card. Each networking card has a MAC address assigned to it during it's manufacturing, and thus it does not change when a computer moves between networks (unlike an IP address which is assigned by the network). A few things to note: - A computer only has a MAC address if it has a physical or virtual network card - A computer has as many MAC addresses as it has networking cards - MAC addresses CAN be modified before being broadcast to the rest of the network, however generally this results in the computer not receiving intended traffic and requires specialized software
How are URLs assigned to IP addresses?
URLs are assigned randomly to differently IP addresses. IP addresses are the numbers that identify a person's location online; it gives the general location and device.
How long are Ethernet Mac addresses?
Ethernet addresses are 48 bits long - not 32 bits long like IP addresses. Different single network standards have different address lengths. Ethernet addresses are called MAC addresses for other reasons, Media Access Control.
How did you determine the IP address for your printer?
IP addresses are normally assigned dynamically by the router.
What types of problems could result from having a mixture of statically assigned and dynamically assigned addresses on same network?
The only problem you might run into, is statically assigning an ip address that is in the dhcp address pool. Make sure you know what the dhcp pool is, and assign static addresses outside of that range.
How does a switch interface that uses sticky port security handle MAC addresses?
They are configured dynamically and are saved in the running configuration.
What two methods can be used to remove MAC address table entries from a switch?
Power cycle the switch to clear all dynamically learned addresses, and the clear mac address table command will remove statically and dynamically configured table entires
How do bridges and switches dynamically create their table?

What is composed of the remaining addresses within a dhcp scope once all exclusion ranges have been applied?
The remaining addresses form the Available Address Pool which can then be dynamically assigned to DHCP clients
Does the BOOTP require that IP addresses be assigned manually at each client?
No it does not.It relies on a static table to associate IP addresses with the MAC.
What is a possible impact of setting too short an aging time in the MAC address table of a switc?
impaired ability to dynamically learn new addresses

MAX addresses are assigned to a device's NIC at the factory by its manufacturer?
That would be MAC address, which stands for Media Access Control. It is assigned by the manufacturer. The manufactur's are provided with a range to use.
What do most networks use to dynamically assign addresses?
DHCP
What bit addresses are assigned to P0?
Addresses 80 - 87H are assigned to the P0 port
