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.[1]

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

Some popular Looking Glass implementations are in Perl,[2] PHP [3][4] and Python [5][6] publicly available on GitHub.

The operator class would be good enough. It is better to define a new class with access to specific commands to restrict the looking glass user to what it actually needs (no more, no less).
