Google/search dns look up for sites that let you trace/look up ips dns stuff and put the website in and you will get an IP number that you can put into your browser and that will take you to the page. I put in this blog but it only comes up with the IP for google, the owners of the blog. I'd need to buy my own domain name for it to work for the blog.
Some ip's you should have are news sites you trust, .gov sites, chat sites, forums and banking sites. I think bank sites are important because I can see it being a big reason for the .gov to switch off the dns servers to stop runs on banks, think Northern rock. News and .gov so you can find out information and chat sites so you can share and really find out whats going on.
I'm not the best for explaining stuff on here, if you don't understand anything let me know in comments or email me and I'll see if I can do a better job. Nows the time to figure this stuff out, before they switch off the dns servers.
I'll get you started, any one wants to add to this list please put it in comments and I'll update it.

ETA Been awhile since I had to do this, seems you can only find the front pages of web sites. I.e bbc front page not bbc news. Once at the front page you can navigate around the site no problems, just thought I'd mention it to make it easier for when your looking up the ip's.
