Using nslookup to query DNS records
I recently purchased TCP/IP Illustrated, Vol 1: The Protocols (Highly suggest picking this up, it’s extremely insightful, and I hope to learn a LOT more about TCP in the near future) and have been diving into networking as a whole a lot more; one such piece of text I read was on the Windows ‘nslookup’ tool I hadn’t previously known much about.
Normally to find the IP address for an A record, you could enter ‘nslookup google.com’ which would return the A record for that FQDN. Here’s where the cool bit comes in. You can actually use nslookup like the Linux ‘dig’ function by using the ‘set type=x‘ option from within nslookup
nslookup Default Server: google-public-dns-a.google.com Address: 188.8.131.52
> set type=a
Nslookup can be used to lookup any DNS record type. Just some food for thought.
