If you are looking for what it might be used for, it is imperative that you understand what Npcap Loopback adapter is and how it works. This way, you can classify the applications in a better manner.
What Is Npcap Loopback Adapter Used For?
Npcap is the best thing that you can get as it is able to sniff loopback packets. These loopback packets are about the transmission between the services on the same machine. That means, if you are using different services or applications on the same computer or the PC, they might be interacting with each other as well. These data packets that are being sent or received are covered on the Windows Filtering Platform. After you have it installed, Npcap will create an adapter on your PC settings and it will be shown as Npcap Loopback Adapter.
Keeping an eye on the traffic

There might be some services that can cause you to have problems if there are issues with them. This is simply the optimal way to keep an eye on the inter-services communications as well as making sure that the network is optimized the right way as it should be.

Npcap is one of the best things to have on your PCs if you are concerned about the network security. It allows Administrators only to sniff the packets that are being transferred over the network. This way, other users with the credentials will also not be able to sniff any packets and have access to the communication that is being done on the inter-services part. This extra layer of security can be disabled or enabled according to your choice.
