Record Sets
Record sets are a collection of records in a hosted zone that share the same name and type. They are used to define how resources, such as web servers or mail servers, should be accessed by clients. Each record set can contain multiple records, which have different values depending on the routing policy you choose. Amazon Route 53 supports various types of records, including A, AAAA, CNAME, MX, PTR, SPF, SRV, and TXT records. You can create, modify, or delete record sets using the Route 53 Management Console, APIs, or AWS CLI. When you make changes to a record set, Route 53 automatically propagates the changes to all its DNS servers worldwide within 60 seconds, ensuring that clients always have access to the most up-to-date information about your resources.
