i have several questions regarding IP and networking and stuff

i live in one of the flats within a compound, here in the Philippines. Our landlord has a T3 connection hosted by PLDT-an ISP. To access the net and save on finances, we have a network within a compound.
So my questions..
1st Q: how to determine if IP is dynamic or static. (note: my TCP/IP is already configured to auto obtain IP add, DNS, etc)
2nd Q: is there a program which forces a dynamic IP add?
3rd Q: i've tried programs like hide-IP but this doesn't really help me much at all, are there any other programs?
please note:
a. as much as i want to, i cannot access the router, so i can't turn it off to have my IP renewed..
b. i also tried the ipconfig flushing thing but when i check www.whatsmyip.com, my IPadd is still the same..
