# Resource Record

Resource records are used by [Domain Name Systems](/glossary/d/dns) to identify and manage domain data.

Each record has name, number, [time to live](/glossary/t/ttl), a class, and data specific to its [type](/glossary/r/record_type).

The transmission format for resource record is specified in [RFC 1035](https://tools.ietf.org/html/rfc1035).
