Nslookup–the Ultimate DNS Troubleshooting Tool
Ever need to troubleshoot DNS related issues? Nslookup is the tool for you, and today I cover how to use this powerful little tool, along with some real-world examples.
This is part 3 of a 52 Web Pro Series for the web administrator. Previous walkthroughs include:
Week 1 – Ping and Tracert
Week 2 – Understanding DNS zone records
All future videos can be found on the Web Pro Series landing page.
I’ll call this a “201 level” walkthrough although I haven’t decided yet how I’ll classify each week’s video. This doesn’t require too much previous knowledge but it does move quickly and digs into DNS quite a bit—at least as much as can be done in about 10 minutes.
