Contact your ISP. – SLaks Jul 27 '11 at 16:41

You need to ask your ISP for a static IP address.
They are likely to charge extra for it.

Alternatively, you could use a dynamic DNS provider, such as No-IP, which will give you a domain name that always resolves to your IP address.

The problem is that most programs use reverse DNS for checking the access list, and changing it requires a static address too. – grawity Jul 27 '11 at 16:46
The chances are virtually nil that he needs to worry about a PTR record. It is almost certainly that the company's firewall just restricts connections to a specific IP. I have never heard of a firewall checking a PTR record (reverse DNS) in this case. – KCotreau Jul 27 '11 at 17:00
PTR records are typically only necessary for mail servers. – MaQleod Jul 27 '11 at 23:05
