How come MAC addresses don't run out -- how do manufacturers know which ones they can reuse?
MAC addresses don't really run out, they get reused, and they distribute to different parts of the world so there is a smaller chance of two addresses being on the same network.
When and where can use the IP-address and the MAC-address?
802.11 use MAC addresses, which are the same as IP addresses in some networks
Why must NIC not share the same MAC address?
No two cards ever manufactured should share the same address. If two cards contained identical MAC addresses problems would be encountered with network communications.
Can two computers have the same MAC address?
NO, its not possible to have same MAC addresses for two different network cards. because MAC address is a unique part of the recognition of the network card and it is also called as PHYSICAL address of your PC. There is possibility of 2 network cards with same MAC address by 3rd party MAC spoofing techniques.........
What are two addresses required for communication in Internet?
logical and mac
What is Mac address of the wireless adapter?
MAC addresses are a kind of serial number. They are supposed to be unique worldwide; that is, two different network equipments, even of the same kind, will have different MAC addresses. They are used for communication, to identify the individual pieces of equipment.MAC addresses are a kind of serial number.

What effect will it have on the network if two devices from two different manufacturer share the last 24 bits of their mac addresses?
It should not cause any problems on the network since the first 24 bits of the MAC addresses are different.

Can you use 2 Mac addresses from one cable at the same time with a splitter if both Mac addresses are provisioned?
MAC address are hard coded on network cards and network devices. A HUB acts as a splitter, so yes. >both Mac addresses are provisioned; Implies your ISP will assign unique IP addresses. The hub then acts as only an electrical connection box. Without Unique IP addresses, you need a router instead of a hub or switch
What is commonly used to restrict access to a network based on the physical hardware address of the clients network device?
You can enable MAC address (also know as Physical Address) filtering. MAC address filtering has two modes: 1. Allow access to listed MAC addresses 2. Deny access to listed MAC addresses.
How many Mac addresses are possible?
This 48-bit address space contains potentially 248 or 281,474,976,710,656 possible MAC addresses.
Can computers have the same MAC address on a server?
No, they can't have the same mac address, because mac address is an id for a machine therefore the ip addresses are registered to the DHCP table accordingly to the mac address. So if you spoof the mac address lets say having two machines with the same mac address what will happen is that only one machine at time would be allowed once it disconnect then the other can connect. Why spoofing a mac address? I guess one of the reasons is to defeat a network administrator when they secure their network by filtering the mac addresses so by spoofing the mac address you will be able to access the internet.
