I'm going to get arrested for this

http://blackhole-1.iana.org/ - Looks like fun
pipedreams.dea.gov - Pipe Dreams? Are they high?
http://208.255.166.219/ - No, that website is not blocked. That is the page they redirect blocked sites to.
http://ready.gov/ - I can’t resist posting this one. Call 1-800-BE-READY (seriously).
