Troubleshooting Domain Resolution Issues

There’s a lot of different tools and ways that will help you while troubleshooting domain resolution issues, so let’s take a look at some of them.

It may sound silly, but a lot of people that complain about their domain not working properly when they try to visit their website have this problem. If your site doesn’t load the first thing you have to check is that you’re using the right Name Servers, which should be provided by your hosting/service provider.

Remember that the Name Servers may take up to 24-48 hours to propagate around the world after you’ve assigned them to your domain.
To check if your domain is using the right Name Servers or not, use a tool like whois or just verify in your registrant’s control panel.

Use Dig command

Dig is a great tool to check DNS records and troubleshoot DNS records issues. For example to check the A record of your domain, open your system’s console application and type:

dig A
