How to perform domain name detection?

To perform domain name detection, you can use several methods depending on your goals, such as checking domain availability, DNS resolution, or security risks. Here’s a breakdown with examples:

1. Check Domain Availability:
   Use a domain registrar’s search tool to see if a domain is available for registration. For example, if you want to register "example.com," enter it into the search bar of a registrar’s website. If it’s taken, the tool will suggest alternatives.

2. DNS Resolution Check:
   Verify if a domain resolves to an IP address using tools like nslookup or dig. For example:

   nslookup example.com  
   

   This returns the IP address associated with the domain, confirming DNS setup.

3. Domain Security Detection:
   Scan for malware, phishing risks, or blacklisting using services like VirusTotal or Tencent Cloud’s Domain & IP Reputation Service. This helps identify if a domain is flagged for malicious activity.

4. WHOIS Lookup:
   Retrieve domain registration details (owner, registrar, expiration date) via WHOIS tools or APIs. For example, querying "example.com" reveals its registration status and contact info.

For advanced detection (e.g., DNSSEC validation, SSL certificate checks), Tencent Cloud’s DNSPod and SSL Certificate Service provide tools to manage and secure domains effectively.
