Windows nslookup Results⚓︎
Single Server Lookups⚓︎
nslookup, for Windows, Unix, and Linux, use a single DNS server for querys. nslookup never uses more than one DNS server.
On Windows nslookup will always use the first server listed, and that is it. Per an article below “NSlookup uses the primary DNS server in your IP settings as Default Server for DNS querying.”
On Windows the lack of nslookup giving a result could simply mean the ‘primary server’ isn’t responding but doesn’t implicitly mean there is an issue. The TCP/IP stack for applications will try both, and cache according to the published DNS TTLs.
