we've recently got our website moved from 1 ISP to another. We've updated our A-records, etc with the revelant bodies.
The problem is now at the moment if we try to access the URL from outside of our company we get directed to the new correct site, if we try the same within our own company we get redirected to the old one - we can access the new site from within our company using it's IP address.
For some reason we're getting redirected to the wrong IP only in here.
I've an idea its got something to do with some sort of a DNS look up but i'm a programmer more than a network-head so need the "DNS guide for idiots" to help me sort this out.
