How DNS Resolvers work ??
I was searching & trying to learn about DNS Systems but not getting much information.
Suppose, I setup 4 DNSOnly Servers in 3 Different regions e.g. US, EU (2), APAC. I set them as following:
ns1 = us
ns2 = eu
ns3 = eu
ns4 = apac
ns1 = us, eu (2 ipv4 in 1 nameserver)
ns2 = eu, apac (same as above)
If the visitor is from India/Singapore, will it resolve from the APAC Region server ?? Or, it can take any of the 4. If the visitor from India gets the domain resolved from us dns server, then there should be no advantage.
Also, I want to how Domain resolves from a visitors internet browser. Can anyone explain it in a sequencial form ?? I mean, I know that how it is done but when there is more than 1 nameserver & the zones are different then how is it done ??
