Values specific for simple records
When you create simple records, you specify the following values.
Routing policy
Choose Simple routing.
Record name
Enter the name of the domain or subdomain that you want to route traffic for. The default value is the name of the hosted zone.
Note
If you're creating a record that has the same name as the hosted zone, don't enter a value (for example, an @ symbol) in the Name field.
For more information about record names, see Record name.
Value/Route traffic to
Choose IP address or another value depending on the record type. Enter a value that is appropriate for the value of Record type. For all types except CNAME, you can enter more than one value. Enter each value on a separate line.
You can route traffic to, or specify the following values:
A — IPv4 address
AAAA — IPv6 address
CAA — Certificate Authority Authorization
CNAME — Canonical name
MX — Mail exchange
NAPTR — Name Authority Pointer
NS — Name server
The domain name of a name server, for example, ns1.example.com.
Note
You can specify an NS record with only simple routing policy.
PTR — Pointer
SPF — Sender Policy Framework
SRV — Service locator
TXT — Text
For more information about the above values, see common values for Value/Route traffic to.
Record type
The DNS record type. For more information, see Supported DNS record types.
Select the value for Record type based on how you want Route 53 to respond to DNS queries.
TTL (seconds)
The amount of time, in seconds, that you want DNS recursive resolvers to cache information about this record. If you specify a longer value (for example, 172800 seconds, or two days), you reduce the number of calls that DNS recursive resolvers must make to Route 53 to get the latest information in this record. This has the effect of reducing latency and reducing your bill for Route 53 service. For more information, see How Amazon Route 53 routes traffic for your domain.
However, if you specify a longer value for TTL, it takes longer for changes to the record (for example, a new IP address) to take effect because recursive resolvers use the values in their cache for longer periods before they ask Route 53 for the latest information. If you're changing settings for a domain or subdomain that's already in use, we recommend that you initially specify a shorter value, such as 300 seconds, and increase the value after you confirm that the new settings are correct.
