When I see route 53 records. like following data existed. But I couldn't understand how to read them. I understand A
records represents domainname's IPv4 address. but 123xyz.cloudfront.net.
was represented in this record. What is this?
Record name Type Routing policy Differentiator Value/Route traffic to
beta.test.example.com A Simple - 123xyz.cloudfront.net.
beta.test.example.com AAAA Simple - 123xyz.cloudfront.net.
beta.test.example.com NS Simple - ns-1037.awsdns-01.org.
ns-891.awsdns-47.net.
ns-1996.awsdns-57.co.uk.
ns-113.awsdns-14.com.
I still haven't understood how to read them. if someone has experienced same issue, will you please let me know. thanks
The two most popular types of DNS entries are:
A-Record
, which resolves the domain name into an IP address CNAME
, which tells DNS start start the domain name resolution again with a different DNS Name (eg point www.example.com
to example.com
However, a domain apex (when it does not have a subdomain at the front) cannot have a CNAME
record -- this means it is not possible to point example.com
to www.example.com
. Amazon Route 53 overcomes this with the concept of an Alias , which allows a domain apex to point to Amazon S3, Amazon CloudFront and a few other services:
Your DNS entries are saying:
A
record resolves beta.test.example.com
to 123xyz.cloudfront.net
(using an Alias) AAAA
record does the same, but for IPv6 NS
record points to the Name Servers for the Domain Name
