How DNS resolution works when comes to geoghraphic location

[bkumarroy]

Hi,

I need a help on "How DNS resolution works when comes to geographic location"

I have four gateways "Active-Active" each located in four geographic regions. All are redundant. When i query with the FQDN of the gateway it returns me four IP addresses.

So my question is if i am moving from one geographic location to another then will the DNS query will return me, first the IP address of that particular geographic location in which i am in. If so how does the DNS function like this. Please explain me in detail.

Thanks in advance

DNS doesn't care where you are located. When you resolve the FQDN it will try the first address that is configured in DNS.
