This is a syntax format for writing a Resource Record (RR) in the Domain Name System (DNS).
- “name” refers to the domain name that the record belongs to, such as example.com.
- “TTL” stands for Time-to-Live, which is the amount of time in seconds that the record should be cached by DNS servers before being refreshed.
- “rr_type” indicates the type of RR being created, such as A (IPv4 address), AAAA (IPv6 address), MX (mail exchange), CNAME (canonical name), etc.
- “value” is the data associated with the record type, such as an IP address or hostname.
Here’s an example:
example.com. 3600 IN A 192.0.2.1
This creates an A record for example.com with a TTL of 3600 seconds (1 hour), pointing to the IPv4 address 192.0.2.1.
