GeoLocation. Geolocation resource record sets only: A complex type that lets you control how Amazon Route 53 responds to DNS queries based on the geographic origin of the query. For example, if you want all queries from Africa to be routed to a web server with an IP address of 192.0.
What is AWS DNS

What is the difference between alias and CNAME in Route 53

What is an alias record used for
An ALIAS record is a type of DNS record that points your domain name to a hostname instead of an IP address.
Should I use CNAME or A record
General rules: Use an A record if you manage which IP addresses are assigned to a particular machine, or if the IP are fixed (this is the most common case). Use a CNAME record if you want to alias one name to another name, and you don't need other records (such as MX records for emails) for the same name.
