"would that reset my ip as well"
if you have your machine set to a static IP address--then the answer is no.
other than that--broadband internet connections are based on the IP address of the 'modem' and most people just use the standard router configuration with dynamic IPs for their machines through the DHCP server settings--if you have a 'static' IP address on your machine, you will need to reset it to 'obtain IP address automatically' in your network connection control panel and possibly also change DNS server to 'obtain DNS server address automatically (I believe the DNS server will automatically change when you change the 'obtain IP address..' setting)
