Nslookup examples

If you submit a query for a non-existent host name you will receive the following

response:

 
C:\>nslookup thisdoesnotexist.coatbank.com
Server: dc1.coatbank.com
Address: 192.168.0.100
*** dc1.coatbank.com can't find thisdoesnotexist.coatbank.com:
Non-existent domain
 

If you want to troubleshoot a DNS server other than the one specified for the primary

connection on the local client computer, you can specify the DNS server using the Nslookup command, eg: the following command executed at the command prompt queries the DNS server at 207.46.138.20 for the name www.microsoft.com:

 
C:\>nslookup www.microsoft.com 207.46.138.20
 

You can also use Nslookup to resolve IP addresses to host names, eg: the command below returns the FQDN associated with IP address 207.46.249.222:

 
C:\>nslookup 207.46.249.222
Server: localhost
Address: 127.0.0.1
Name: www.microsoft.com
Address: 207.46.249.222
