DNS NSLookup
This is a Windows tool.
To lookup TXT Records
nslookup -q=TXT tester.jbstafford.co.uk 8.8.8.8
nslookup -type=TXT tester.jbstafford.co.uk 8.8.8.8
Different Server
Query a different DNS server than the one specified in Windows
nslookup www.google.com 1.1.1.1
Other
Query a different DNS server than the one specified in Windows
nslookup > set norecurse >www.google.com
Different Port
In theory, you can use “set port=5353” to tell nslookup to query port 5353 instead of port 53. However, this documented feature is broken in Windows and doesn't work. Use dig instead.
TTL
To find the TTL of a DNS record, use
nslookup -debug www.example.com
You will see TTL in there and possibly Default TTL
Debug
set debug
set nodebug
End Dot
When you don't put a . at the end of the query, Microsoft will test “domain”.“DNS Suffix”. If you do put a . at the end, Microsoft will only query what you type.
e.g. if you are connected to a network that hands out example.com as the DNS Suffix and you lookup www.google.com, then the first DNS lookup is for www.google.com.example.com. However, if you lookup www.google.com. (note the . on the far right) then it will only lookup www.google.com.
