Question

This is a really simple question, but I cannot find any mention of this, anywhere..

How do I get the client’s IP address from in Sinatra?

get '/' do
    "Your IP address is #{....}"
end

Answer 1

Sinatra provides a request object, which is the interface to the client request data that you should be using.

Using request.ip is the preferred method to find the client’s IP address:

get '/' do
  "Your IP address is #{request.ip}"
end
