Can two devices have same MAC address?

In order for a network device to be able to communicate, the MAC Address it is using must be unique. … If two devices have the same MAC Address (which occurs more often than network administrators would like), neither computer can communicate properly. On an Ethernet LAN, this will cause a high number of collisions.

Does VPN change MAC address?

When VPN is used it really does not affect or hide your device’s MAC address, but it does not need to do it anyway since in the long device chain your MAC does not travel any further than your router. … If you want to really protect yourself you could use a VPN to hide your IPv6 address or try to spoof your MAC address.

What does a MAC address contain?

A MAC address is a hardware identification number that uniquely identifies each device on a network. The MAC address is manufactured into every network card, such as an Ethernet card or Wi-Fi card, and therefore cannot be changed.

Is a MAC address sensitive information?

Probably not. The MAC address is a unique 12 character string assigned by the manufacturer. Unless your device has been granted access to some secure network based solely on its MAC address… giving it out should not be a problem.

Why is a MAC address important?

The MAC address is an important element of computer networking. MAC addresses uniquely identify a computer on the LAN. MAC is an essential component required for network protocols like TCP/IP to function. Computer operating systems and broadband routers support viewing and sometimes changing MAC addresses.

Is Bluetooth address same as MAC address?

MAC addresses are already quite predictable, easily sniffable, and any form of authentication dependent on them is inherently weak and shouldn’t be relied upon. MAC addresses are almost always only used “internally” (between you and your immediate gateway).

How hard is it to spoof an IP address?

For end users, detecting IP spoofing is virtually impossible. They can minimize the risk of other types of spoofing, however, by using secure encryption protocols like HTTPS — and only surfing sites that also use them.

Is a MAC address unique?

The IEEE manages MAC addresses. The hardware identification addresses that the IEEE distributes are unique. That makes the probability of matching MAC addresses zero. … This means that it is possible for two machines in the same network to have the same MAC address.

How many characters are in a MAC address?

The MAC address is a string of usually six sets of two-digits or characters, separated by colons.
