.cc domains

I am e-mailing you in regards to some mail I received a few days ago. A company named Enic sent me something saying to be sure to register my current URL with the new .cc domains. They claim that IANA is responsible for assigning this new top level domain, yet it is not mentioned anywhere on your website. Please let me know what these are and if there will be more top level domains down the road. My current URL is www.riordanco.com and I would hate to see someone get a hold of this name in the .cc domain. It could really hurt business. My site is under construction right now, but will be up and running soon. sfontana@riordanco.com
