We Build Pages has created a very nice free tool that analyzes backlinks, showing unique domains linking to the site, the IP addresses of those domains (great for analyzine Class C IP structure), and the age of the domains linking to your site. This can also be a good way to analyze the backlinks of your competitors. I do hope they decide to give the tool a better name - Tool Number 9 just doesn't work. In any case, have fun playing with backlinks at www.555webtemplates.com/backlinks-tool.asp
