Ping Domain Showing Old IP Address

Yesterday a member complaint that he could not used a FTP client to log in his account for a few day. He tried to do a ping to his domain but returned the old IP address that used a few month ago.

ping hisDomain.com

pinging hisDomain.com [xxx.xxx.xxx.xx] with 32 bytes of data:

Request timed out.
Request timed out.
Request timed out.

Where xxx.xxx.xxx.xx is the IP address of the old server that used a few months ago.

Actually this is not the problem of our web server or domain configuration. This is impossible that the DNS records are still not updated.

He is using Windows XP. This was quite clearly that the old IP address was stillĀ  caching in his computer. To solve this problem, simply refresh the memory of the ip configuration in his computer.

1. Click Start -> Command Prompt

2. Enter the following command:

ipconfig /flushdns

3. Ping the domain again.

The pinging now should return the correct IP address now.
