Is there a global DNS server?

What is the difference between latency-based routing and Geo DNS?
Amazon maps-out typical latency between IP addresses and AWS regions. Choose Latency-based Routing to have the fastest response. Geolocation maps the IP addresses to geographic locations. This permits rules like “send all users from Côte d’Ivoire to the website in France”, so they see a language-specific version.

A DNS zone is also an administrative function, allowing for granular control of DNS components, such as authoritative name servers.
What is geolocation in AWS?
A complex type that contains information about a geographic location.
Are IP addresses assigned geographically?
IP addresses on computer networks do not represent specific geographic locations. It is still theoretically possible, however, to determine the physical location of IP addresses in many (but not all) cases.
What is the difference between primary zone and secondary zone in DNS?
Primary DNS servers contain all relevant resource records and handle DNS queries for a domain. By contrast, secondary DNS servers contain zone file copies that are read-only, meaning they cannot be modified.
What is Geo DNS and how do I use it?
You can also target responses to individual country granularity. Geo DNS can be enabled for all of the supported RRTypes including A, CNAME, MX, TXT, SRV, NAPTR, and CAA. Be aware that Geo DNS is not an exact science. GeoDNS will key off the remote IP address of the resolver making the query.
Can I create DNS policy for geo-location based traffic management?
You can use this topic to learn how to create DNS policy for geo-location based traffic management when your DNS deployment includes both primary and secondary DNS servers.
How do secondary DNS servers redirect traffic based on Geo-location?
Now the secondary DNS servers are configured with the required DNS policies to redirect traffic based on geo-location. When the DNS server receives name resolution queries, the DNS server evaluates the fields in the DNS request against the configured DNS policies.
How does DNS work with a web server?
Instances of the Web server might be located in different datacenters at different physical locations. DNS can assess the client and Web server locations, then respond to the client request by providing the client with a Web server IP address for a Web server that is physically located closer to the client.
