I know there is no such thing as a stupid question, but

...may I ask a goofy question?

I have been getting alot of inbound traffic for "localhost". I need an analogy please. Is that like the computer / router talking to itself? Or could the inbound be from a site that I have blocked by my host file?

Thanks

localhost refers to your computer wich is also known has 127.0.0.1

A placeholder for the name of the computer on which a program is running; localhost uses the reserved loopback IP address 127.0.0.1.

(127.0.0.1): Localhost, or the loop back IP address 127.0.0.1, is traditionally assigned to the local host, meaning that the operating system (OS) will route information destined for localhost to the port on the same machine and will never even reach a NIC. In fact, a NIC is not required to have a localhost.
