Some cool sites you can use to search for domain names, dns records, and much more are: DNS Report, DNS Stuff, NetLingo (dictionary of internet words), TekTips (search for worldwide domains in one place).
The last bit of news which is interesting is that GoDaddy is apparently the #2 registry for domain names, passing (I think) Register.com and right behind Network Solutions. I think this is for the number of domains registered, as GoDaddy has been #1 in new domains for a while now.
– Thanks Kent for showing these sites.
