Amazon Route 53 is a scalable and highly available Domain Name System (DNS) web service. It is designed to give developers and businesses an extremely reliable and cost-effective way to route end users to internet applications.
Here are some of the most common record types in Route 53:
A Record (Address Record): This record is used to point a domain or subdomain to an IPv4 address.
AAAA Record (Quad A Record): This record is used to point a domain or subdomain to an IPv6 address.
CNAME Record (Canonical Name Record): This record is used to forward one domain or subdomain to another domain name. It's often used to ensure that multiple domain names always show the same information.
MX Record (Mail Exchange Record): This record is used to direct a domain’s email to the servers hosting the domain’s user accounts.
NS Record (Name Server Record): This record is used to point a domain or subdomain to a set of name servers that are responsible for its DNS records.
PTR Record (Pointer Record): This record provides the capability for an IP address to resolve to a domain or hostname. It's primarily used for reverse DNS lookups.
SOA Record (Start of Authority Record): This record contains administrative information about the zone, including the primary name server, the email of the domain administrator, the domain serial number, and several timers related to refreshing the zone.
SRV Record (Service Record): This record is used to define the location of servers for specific services, such as IMAP, SIP, FTP and others.
TXT Record (Text Record): This record is used to hold some text information. It can be used for various purposes. For example, it's often used to verify domain ownership and set up email spam prevention measures.
CAA Record (Certification Authority Authorization): This record allows a domain name holder to specify one or more Certification Authorities (CAs) authorized to issue certificates for that domain.
Remember, the usage of these records depends on the specific requirements of your applications or services.
