Are you trying to secure your Rails app via IP?

You can use request headers in Rails to compare. You would have to use  
regex to compare for specific range. But it would be wiser to keep  
this out of Rails and do in Apache mod\_proxy or whatever else you are  
proxy-ing with.

Wow, talk about square peg, round hole. No, RoR doesn’t have a  
method/API/call/etc to do that. Do what everyone else does: use nmap.

What do you mean by ‘scan my network’?
