Resolving Common DNS Issues
DNS problems can prevent users from reaching your website even if your server is online.
Using `dig` to Check Records
The `dig` command is a powerful tool for querying DNS records.
# Check the A record for your domain
dig yourdomain.com A +short
# Check the MX (mail) records
dig yourdomain.com MX +short
# Check nameservers
dig yourdomain.com NS +short
Using an External DNS Checker
Online tools like dnschecker.org can check your DNS records from multiple locations around the world, which is great for seeing if your DNS changes have fully propagated.
Common Problems
- Wrong IP Address: The A record doesn't point to your server's IP.
- Slow Propagation: DNS changes can take time to update globally.
- Incorrect Nameservers: Your domain is not pointed to the correct nameservers where your DNS records are hosted.
