Hi,

I'm trying to find out what an ISP uses for it's IP address range given to connecting users.  The reason is that I want to use my home account to connect to our work server (by terminal services) and I want to restrict the firewall to only allow my ISP's range.

I've contacted the ISP but not having much luck.  Is there any way to find this out?

Regards,

Paul.

Go to http://www.whoisview.com/products/whoisview/whoisview_online.php and enter an address that you know belongs to them. It should give you the whole block.

Hope this helps.
