As far as IP addresses go, the world is fast running out of IP addresses. This is all because of the increasing number of internet users. Time will come when people can’t log on to the internet except people who are already logged in, log out. Scary thought eh! But don’t be ’cause help is on the way.
We are currently using the IP version 6. However, some engineers in China are working on a new IP version, the IP version 4 which should eventually be able to work along side the IP v 6. Kinda cool.
