Internet Explorer Keywords for DNS Troubleshooting

I think its safe to say that DNS is part of the fabric of the internet. I don’t remember how many times I had (or helped someone with) issues with public DNS, but I can assure you that it has been a lot. DNS controls everything about your domain, from the correct resolution of your website to where your email should go.

My two favorite sites for troubleshooting public DNS issues are and These two sites have saved me in numerous occassions and whenever somebody is having some DNS issue they are my first stop to help determine the problem. I encourage you to familiarize yourself with each site… I can assure you that you will find them as useful as me. Did I mentioned that both sites are free? 🙂

Ok. So, those sites are old news for you? Well… I have something here that you might like. I “borrowed” an idea from Susan’s blog and created a registry file that adds a set of keywords to the IE address bar so you can use this site even faster.

Right click here, select “Save As” and save it to your desktop renaming the extension to .reg (alternatively you can just click the link to see what we are adding to the registry). Double click on the file and allow it to be imported into the registry. That’s it! You can now open IE and use the following keywords to do amazing stuff…

DNS – Generates a DNSReport for that domain

A – A record for that hostname

MX – MX record(s) for that domain

PTR x.x.x.x or – Reverse DNS records for that IP/Hostname

WHOIS – Registration information about a domain

So, do you think this is useful? Comment below and let me know what you think!
