IP addresses have been at the core of the Internet. Basically, IP addressing is the assignment of a logical address to a physical device. Two devices on a network can exchange information since each of them has an Ethernet address that is unique to the physical network. Much like how the mailman can distribute letters to various mailboxes as long as he has the address. The Internet also works in the same way. IP addresses are assigned to every device we use (computers, phones) and every site we visit (websites, email servers).
Many users ask, can two computers have the same IP address? As we know, every computer has a different IP address. Usually, two computers will not be associated with the same IP address on the network. If one user gives access to others, it’s easy to use the same IP address from different locations. Here we have mentioned the method of using the exact IP address for two devices.
What Is An IP Address Conflict?
An IP address conflict is when two IP addresses use the same IP address. Two IP addresses can have IP address conflicts in two different ways:
- Public IP address conflict: On public networks, there is no problem if two IP addresses are using the same IP address. You see ipv4 private IP address conflict.
- Private IP address conflict: A device using ipv4 private IP address conflict can’t communicate to other IP addresses. Private IP address as ipv4 IP address range from 192.168.0.1 to 192.168.255.254.
What causes an IP address conflict?
Every person has a different fingerprint. Likewise, each device has a different IP address. No matter if it’s mobile or computer. Although multiple devices are allowed to browse under a specific IP, sometimes it can be face trouble.
If several devices are assigned with a single IP that is allowed to use personally, in this situation, the last joined device might be unable to interact with other devices.
As a result, it receives an error, which is also known as an IP address conflict.
Is IP address conflict dangerous?
With IP address conflict, you have some issues with security, speed, and performance. If two computers share the same ipv4 addresses, then they can’t transmit information between them.
If two computers not connected to the same network have the same IP address, both will face problems. Even if it’s a minor problem for personal computers, it can be a big problem for companies that use servers and other devices with several addresses. They can cause loss of data or interrupt Internet access in some cases.
How to avoid IP address conflict?
To avoid IP address conflict, you must use a tool like IP address conflict detection. The tool will detect two computers with the same IP address and warn about the possibility of an IP address conflict. After installing this kind of application on your computer, you can easily solve IP address conflicts.
