IP-addresses stored as int results in overflow?

Question

I\'m writing a chat-server in node.js, and I want to store connected users IP-addresses in a mysql database as (unsigned) integers. I have written a javascript method to convert

Answer 1

You shifted left to get the original number - which is just 4 sets of bits regardless of the sign.

Shift right to get back to the IP. Doesn't matter what the sign is.
