DNS, or Domain Name System, is a hierarchical and distributed naming system for computers, services, or other resources connected to the Internet or a private network. It associates various information with domain names assigned to each of the connected devices using the Internet Protocol (IP) address. DNS translates domain names to IP addresses so browsers can load Internet resources.
Checking your DNS is important for troubleshooting network connectivity issues, ensuring that your devices can resolve domain names to IP addresses correctly. Here are some methods to check your DNS:
- Use the command prompt or terminal:
nslookup google.com
Use a third-party DNS lookup tool, such as MXToolbox or DNS Checker.Check your router’s DNS settings.
If you encounter issues with your DNS, you can try the following troubleshooting steps:
- Restart your router and modem.
- Flush your DNS cache:
ipconfig /flushdns (Windows)
sudo dscacheutil -flushcache (Mac)
Change your DNS servers to a public DNS service, such as Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1 and 1.0.0.1).
1. Tools
To effectively check your DNS, utilizing the appropriate tools is essential. The command prompt, third-party tools, and router settings offer various methods to examine your DNS configuration and identify any potential issues.
