localhost is a hostname that resolves to the IPv4 address 127.0.0.1 or IPv6 ::1 . It represents your own computer. Traffic sent to localhost never leaves your machine. This is critical for security: no external entity can intercept the connection because the network stack loops the packets internally.
The phrase typically refers to a local development or administrative service running on your own computer (the "localhost") using port 11501 . The "verified" status indicates that a secure HTTPS connection has been successfully established and the security certificate is recognized as valid by your browser or system .
