Checking your site’s DNS via SSH
You can check your site’s DNS values with the commands listed below. An SSH terminal is required to execute these commands. For more information, see the SSH overview page.
Checking nameservers This command examines the current location of your site’s nameservers. The +short option reduces the output to just the nameservers.
[server]$ dig ns example.com +short ns2.GreggHost.com, ns1.GreggHost.com, ns3.GreggHost.com, ns4.GreggHost.com, ns5.GreggHost.com, ns6.GreggHost.com, ns8.GreggHost.com, ns9.GreggHost.com,
This examines the location of your site’s A records (IP addresses).
188.8.131.52 +short [server]$ dig example.com
184.108.40.206 +short 220.127.116.11 [server]$ dig www.example.com
The host command can then be used to determine where that IP address is hosted.
[server]$ domain name pointer apache2-emu.tool.GreggHost.com 18.104.22.168 22.214.171.124.in-addr.arpa
This yields a reverse result. For instance, the IP address is hosted at GreggHost.com, which is shown all the way to the right.
The server name at GreggHost can be found on the left. This indicates that it is hosted on GreggHost’s tool server.
The apache2-emu instance, which the site runs on, is to the left of that.
