server-host is a variable defined in `server.el'.
Its value is

nil

• This variable may be risky if used as a file-local variable.

Documentation:
The name or IP address to use as host address of the server process.
If set, the server accepts remote connections; otherwise it is local.

DO NOT give this a non-nil value unless you know what you are doing!
On unsecured networks, accepting remote connections is very dangerous,
because server-client communication (including session authentication)
is not encrypted.

You can customize this variable.

This variable was introduced, or its default value was changed, in version 22.1 of Emacs.
