Moving Hosts

[Intex]

I've recently attempted to move hosts and it seems as though there's some issues with the speed of page generation.

I previously hosted the website on my own server with a free dyndn domain name. I didn't want to change the domain name so I thought I'd simply change the vbulletin configuration so it reflected the new domain name I purchased as part of the hosting setup and then update dyndns with the new server IP address.

However, it does seem that it's taking ages to update pretty much any forum page, so I'm thinking that there's some coding / mods etc are still calling the dyndns host name.

Is there any way I can track what what pages are going outside of the websites own domain?
