What type of record should be used for subdomains in A records?

 When setting up subdomains in DNS (Domain Name System), A record should be used to map the subdomain to an IP address. Specifically, you should create a separate A record for each subdomain, specifying the subdomain name in the "name" or "hostname" field, and the IP address of the server hosting that subdomain in the "value" or "data" field.

For example, if you have a domain "example.com" and you want to create a subdomain "blog.example.com" that points to an IP address of "123.45.67.89", you would create an A record with the following information:

Name/Hostname: blog.example.com.https://www.site123.com/?aff=14347752 Value/Data: 123.45.67.89

Note that the trailing dot in the "name" or "hostname" field is important, as it indicates that the subdomain is an absolute domain name rather than a relative one. This helps ensure that the DNS resolver knows exactly where to look for the subdomain's A record.
