Build a free Domain Name website in ADSL

If you use ADSL to access the Internet, you can create a free website at home, but the speed is not flattering.

In fact, it is to get the Internet IP address and then update the free Domain Name Information of mycool.net. In this way, when your ADSL Network is disconnected, the new IP address can be promptly updated to your free Domain Name System.

You need to apply for a free Domain Name On www.mycool.net, modify the user name and password in the code, and then run OK.
