If multiple devices are using the same IP address, at least one device will not be able to connect to the Internet.
In cases where there are duplicate IP addresses on the network, you can set up an IDS exception.
To resolve this issue, you will need to change the IP address that your computer is using. You can do this by performing a manual reset of your router (typically just by unplugging it and plugging it back in 30 seconds later) or by using the steps below to issue the release and renew IP commands.
After your IP address is renewed, you should no longer receive notifications about identical IP addresses.
