Do you have websites with the .com domain extension? if so, you should consider hanging onto this domain as the .com is one of the types of domain extensions that is the most valuable. In fact, a website with a .com extension is the most valuable type in the eyes of domain investors, potential individual domain name buyers and Internet domain registration companies. Due to the .com extension already used by millions of sites, other types of domain extensions are becoming more popular and valuable. These would include .net, .uk, .aus, .org, and .edu to name a few. I have a feeling a few of the future types of domain extensions to rapidly grow in value will be something along the lines of .asia, .rus and .chin as these nations, (the Asian market, Russian and Chinese markets) are poised for a huge leap in Internet use. Personally I will be watching closely for these types of domain extensions to begin to grow and this will be the time to grow your domain name portfolio. Actually, now is the time to take a risk and begin to register these domain names and extensions.
