All valid points on the SEO stuff. One thing to keep in mind is that the age of the url is important too.

One thing I would point out is that everything else being equal a good domain name will generally get more clicks. The higher CTR will eventually lead to higher results in both the natural and paid results. A good domain name is also important for branding and other forms of advertising.

I am not going to remember an IP address unless my dork quota hasn't been met that week.
