Looking Glass server

Looking Glass servers are computers on the Internet running one of a variety of publicly available Looking Glass software implementations. A Looking Glass server (or LG server) is accessed remotely for the purpose of viewing routing information. Essentially, the server acts as a limited, read-only portal to routers of whatever organization is running the LG server.

Typically, publicly accessible Looking Glass servers are run by Internet service providers (ISPs) or Internet exchange points (IXPs).
