ping: www.baidu.com: Temporary failure in name resolution

As an AI language model, I don't have access to your local network settings or configurations. However, "Temporary failure in name resolution" error message suggests that the DNS server is unable to resolve the domain name for the website you are trying to ping. This could be due to various reasons such as a temporary network outage, incorrect DNS server settings, or issues with the DNS server itself.

Here are a few steps you can try to troubleshoot the issue:

1. Check your network connection: Ensure that your device is connected to the internet and your network settings are configured correctly.

2. Check DNS server settings: Ensure that your DNS server settings are configured correctly. Try using Google's public DNS server (8.8.8.8) or Cloudflare's DNS server (1.1.1.1) to see if the issue persists.

3. Clear DNS cache: Clear your local DNS cache to force your system to retrieve the latest DNS records.

4. Restart DNS service: If you are using a local DNS server, try restarting the DNS service to see if that resolves the issue.

If the issue persists, you may want to contact your network administrator or internet service provider for further assistance.
