Displays information that can be used to diagnose the Domain Name System (DNS) infrastructure. Before using this tool, you should be familiar with how DNS works. You can use the nslookup command-line tool only if you have the TCP/IP protocol installed.
The Nslookup command-line tool has two modes: interactive and non-interactive.
If you only need to find a piece of data, we recommend using non-interactive mode. For the first parameter, type the name or IP address of the computer you are looking for. For the second parameter, type the name or IP address of the DNS name server. If the second parameter is omitted, nslookup will use the default DNS nameservers.

[no]debug - prints debug information
[no]d2 - Prints detailed debug information

srchlist=N1[/N2/.../N6] - Set the domain to N1 and the search list to N1, N2, etc
root=NAME - Set the root server to NAME
retry=X - Set the number of retries to X
timeout=X - Set the initial timeout interval to X seconds
type=X - Set the query type (e.g., A, AAAA, A+AAAA, ANY, CNAME, MX,

record
view FILE - sorts the output files of 'ls' and uses pg to view them
exit - exit procedure
Query the ns record using a different DNS server
(Note: Because I just did.)Alibaba Cloud's cloud resolution was replaced with DNSPodSome DNS node servers have caches, and all DNS nodes have not been fully updated, resulting in different NS records queried from different DNS servers. ）
List detailed records
The command is as follows:
Query the txt record
The command is as follows:
With many advanced options for testing name resolution and detailed debugging modes for advanced troubleshooting, mastering the program is important for system and network engineers/administrators managing DNS services within their organization.
