As we exit the age of IPv4 and move into the IPv6 generation another change is taking place on the Internet that will be far more visible to most users.
The dot com era may soon draw to an end, and that could lead to some unexpected headaches on corporate networks around the world.The Internet Corporation for Assigned Names and Numbers has been slowly working toward the day when it radically expands the number of top-level domains used on the Internet. There are a few hundred top-level domains today — .com, .net, and .net to name a few — but ICANN wants to expand this to essentially whatever the market will bear.
Today it said that it has received nearly 2,000 applications from companies that want to pioneer these new top-level domains. The new domains would replace the .com’s we have come to know and love with a virtually unlimited of ‘strings’. Think run.nike or drink.coke. The problem is that some of these proposed new top-level domains could overlap with the names used in internal corporate networks. Many of our clients use .lan, .local, and .corp internal active directory DNS domains – all of these tld’s have been requested from ICANN in the new domain offering. Companies are already lining up to take control of the .home and .corp top-level domains, and there is already a lot of Internet traffic looking for computers at those domains.
Other top-level domains that could cause problems include .global, .inc, .prod, .ads, .mail, .site, .host, and .home.
The story is far from over but what we do know is that big change is on the way for the Internet and how we identify and access its resources.
