What happens if 2 devices have the same MAC address?

What happens if 2 devices have the same MAC address?

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. Duplicate MAC Addresses on the same LAN are a problem.

What will happen if two or more devices have similar IP addresses?

If two machines have the same IP address on the same physical network, it’s a problem. Network hardware gets confused about which of those machines really own the IP address. It can refuse to deliver messages at all, or it may randomly choose which of the computers gets each message. This will break most all protocols.

Can multiple systems have same IP address?

As I understand it, two computers cannot have the same public (external) IP address unless they are connected via the same router. If they are connected via the same router, then they can have (share) the same public IP address yet have different private (local) IP addresses.

Can one MAC address have multiple IP addresses?

Yes. You can have multiple IP addresses on one MAC address.

Can IP address be same?

Conclusion : All public IPs assigned to Routers of ISPs or Routers connecting to Internet are unique. but private IPs of two hosts can be the same if both are connected to different public networks.

Why do I have 2 IP addresses?

It’s because your Ethernet (cable) network card and your WiFi network card is just that, two different network interfaces. That means that to function, each of them have to have an IP address, given by your router. It’s normal behaviour.

What does same IP address mean?

A static IP address remains constant, meaning any device using this form of IP will have the same IP address every time they access the internet or connect with other networks. This IP remains in use throughout any device reboots or re-connections, making it a favourite for large business or home networks.

Can a server have 2 IP addresses?

Yes you can have more than one IP address when using a single Network Card. Setting this up is different in each Operating System, but may involve creating a new Network Interface. This can look like a unique connection but will be using the same Network Card behind the scenes.

Is it normal to have 2 IP addresses?

It’s quite simple. It’s because your Ethernet (cable) network card and your WiFi network card is just that, two different network interfaces. That means that to function, each of them have to have an IP address, given by your router. It’s normal behaviour.

Can an IP address be duplicated?

There can only be one public IP, with no duplicates. For example, the IP 8.8. 8.8 cannot be duplicated on the internet.
