What is the reason why some websites can't open?

Some of the Web site why the failure can not open the fault is sometimes because of the domain name after the resolution, but when the local domain name or point to the original IP, this is mainly because of local DNS cache caused, because you have to change the domain name resolution before the domain name. The solution is to update the dns! one is to wait for the computer to update itself (this should have patience, slowly wait, time is not easy to say.) , another way is to manually empty your computer's DNS cache by using a DOS command.

Specific steps:

1, start-run--cmd

2, run: Ipconfig/displaydns, to see what DNS information has been cached on this computer

3, run: Ipconfig/flushdns, empty the DNS cache

After executing the command, the DNS cache information for this machine has been emptied, and we can enter the first command again. Ipconfig/displaydns, you will find that many of the previous records, has now disappeared most of the time, and then enter the previously inaccessible address (note: Other people can access the normal ), is not already able to access the normal!
