Thanks
The Choice module probably is not the tool you want to use. Each Choice activity allows your users to make only a single choice. They can choose a gender or an age , etc - but only one.
You are describing a survey. Moodle has two survey-like tools: "Questionnaire" and "Feedback". Both are third-party tools, and so will have to be installed on your Moodle server. (Ironically, the built-in "Survey" tool won't help you - it only has several predefined surveys.)
The Questionnaire and Feedback modules will also require that the user be logged in before responding.
I would suggest an external survey tool to conduct the survey. You can add a link to it on your Moodle pages.
Two such survey tools are phpESP (phpesp.org) and phpSurveyor (phpSurveyor.org). Both are open source and use PHP and mySql. (There are also several web-based survey services available.)
I believe that the Questionnaire module is based on phpESP. I prefer phpSurveyor, but either will do what you want.
Whoever manages your Moodle installation can handle either of these tools.
The Questionnaire and Feedback modules will also require that the user be logged in before responding.
The Feedback Module by Andreas Grabs does allow guest to respond.

Give the feedback module a try...it may do what you want. I don't think you can restrict by IP, but you can configure it to allow guests to respond. Here is a link to a sample that is set-up to allow guests to reply.

This is actually a very nice module developed by Andreas Grabs...I'm using on a couple Moodle installs. You can get it at the link below.
