Static IP addresses are heavily controled by ARIN and their use must be justified. We don't have static IP addresses that we can easily give out as we need to justify their use to our upstream provider to receive them.
The only valid reason for a static IP address is if you will be having an SSL certificate or an anonymous FTP site.
If you feel you need a static IP address, please submit a Support Ticket explaining why you need one and we will be happy to assist you in getting your site setup with a static address.
