Mixed nslookup Results⚓︎
nslookup, for Windows, Unix, and Linux, uses a single DNS server per execution.
If you re-run nslookup it may choose a different server, but it will never query more than one server at a time. Windows nslookup also only uses the first listed DNS server, it will never query the second server, even when there are timeouts. This is not the case in Linux and Unix, these OSes will test additional servers, only if the previous one timed out.
