4. Find out what DNS server is being used with nslookup. You can use the nslookup command to find out a ton of information about your DNS resolution. One of the simple things to do is to use it to see what DNS server is providing you an answer and which DNS server is NOT.n that case, your DNS Server IP address may be the same as your router. Finally, make sure that your DNS Servers are in the right order. In my case, with the graphic in Figure 2, my local DNS Server is 10.0.1.20. It is configured to forward any names that it cannot resolve to 10.0.1.1, my local router.
