you can track the ip in numerous ways. log files retrieve the ip address via php 'REMOTE_ADDR' or similar google analytics will give you the host name level data
You need to set up a custom filter. Full tutorial here: http://www.roirevolution.com/blog/2006/09/view_visitor_ip_address_in_google_analytics.html
