automated sub-domain creator

I am looking for an automated solution for the website DynDns.com. I need a script/tool that will allow me to create thousands of subdomains from this provider (over a period of time). There are several factors that limit this at present. You are limited to 5 subdomains per account. You also have to enter a unique username / password for each account, and also use email verification. I am looking for a PHP based solution where I can enter a collection of fields and the script will then automate this. (If a different programming language is suitable then I am open to all offers). The account creationm and verification should also be automated. The fields would be along the lines of: - Account username / password - subname - IP I want the sub to be pointed to The script should be flexible in the sense that a list of domains from DynDns can be provided for use (selected randomly), and also IP's can be selected randomly as I will be using quite a lot of different IPs. I want the script/tool to be as secure as possible, using proxies if practical. I also want it to be fast.. ideally I would be able to create at least 50 accounts / 250 subs per day, however a lot more would be better! There is also a problem where after 30 days the subs are effectively wiped out if they are not updated. It would therefore be required for a solution that can log into these accounts 30 days after creation and update them so they stay live. I am looking for a high quality job here. A powerful and secure automated system. I am also hoping for a solution to be done fairly quickly.
