What is IP configuration?

IP configuration is a series of settings between your computer and the network, including IP address, subnet mask, default gateway, DNS server, etc. These settings determine how your computer communicates with the network, and how to access various resources on the internet. Every device connected to the network needs a unique IP address, which is used to identify itself and other devices. If your computer does not correctly obtain or assign a valid IP address, or if there is an IP address conflict with other devices in the network, then the "Ethernet doesn’t have a valid IP configuration” error will occur.
