Answer :

Please use the CLI command 'cmd diagnostics nslookup domain-name-or-ip domain-name' and enter the domain you wish to check.

For example, if we want to check the domain name d2.nebula.zyxel.com on the USG Flex 200HP model, we can issue the CLI command 'cmd diagnostics nslookup domain-name-or-ip domain-name d2.nebula.zyxel.com' to perform the check. Below, you'll find the results: the left side displays the result from the USG Flex 200HP, while the right side shows the result from the Windows PC
