Na ur wrong there mate billing nor tech support will change ur IP Address.
When i spoke to billing and retensions to upgrade me from 120mb to 152mb when it was done i still had the same IP address i've had for months.
The last time my IP address changed was when i put SH2 into modem mode and added my own router which obviously added its own MAC which was different from SH2 causing an IP change and that was about 3 months ago.
