After deleting or pausing the record, why can I still get the IP by executing the ping command to connect to the domain name?

When you delete or pause a record, it may take some time for the DNS (Domain Name System) changes to propagate across the internet. DNS is a distributed system, and it caches records for efficiency. This caching can occur at various levels, including your local machine, your ISP (Internet Service Provider), and intermediate DNS servers.

For example, if you recently deleted or paused a DNS record for a domain, your local DNS resolver might still have the old record cached. Similarly, your ISP's DNS servers might also have a cached version of the record. As a result, when you execute the ping command to connect to the domain name, you might still get the old IP address until the cached records expire or are updated.

To mitigate this issue, you can try the following:

  1. Flush your local DNS cache: On Windows, you can use the command ipconfig /flushdns. On macOS, you can use sudo killall -HUP mDNSResponder.
  2. Use a different DNS resolver: Tools like dig or nslookup allow you to specify a different DNS server (e.g., Google's 8.8.8.8) to query, which might have a more up-to-date record.
  3. Wait for propagation: Typically, DNS changes take up to 48 hours to fully propagate across the internet, though it often happens much faster.

In the context of cloud services, if you are managing DNS records through a cloud provider like Tencent Cloud, you can utilize their DNS management services to ensure more efficient propagation and management of your DNS records. Tencent Cloud's DNS service offers features like fast propagation and low latency, which can help in reducing the time it takes for DNS changes to take effect.
