Private DNS supports several record types to manage domain name resolutions within a private network. These include:
A Records: Maps a domain name to an IPv4 address. For example, an A record can point "example.com" to the IP address "192.168.1.1".
AAAA Records: Maps a domain name to an IPv6 address. Similar to A records but for the newer IPv6 protocol, allowing "example.com" to be mapped to an IPv6 address like "2001:0db8:85a3:0000:0000:8a2e:0370:7334".
CNAME Records: Creates an alias for a domain name. For instance, a CNAME record can be used to point "www.example.com" to "example.com", directing all traffic to the main domain.
MX Records: Specifies the mail server(s) responsible for handling email messages for a domain. An example could be setting "mail.example.com" as the mail server for "example.com".
PTR Records: Used for reverse DNS lookups, mapping an IP address back to a domain name. This is useful for verifying the domain of an email sender or other services.
TXT Records: Used to provide textual information about a domain, often used for verification purposes (like Google Search Console verification) or to specify SPF (Sender Policy Framework) records for email security.
In the context of cloud services, Tencent Cloud's Private DNS service offers these record types to ensure flexible and secure management of domain name resolutions within a private network environment.
