I’m interested in Cloudflare’s load balancing service but I’m wanting to understand the technology a bit more. How does a DNS lookup of, say,
google.com translate to the IP address nearest to me?
If I type
google.com I am directed to an IP that is geographically close to me, instead of being some central server in America, even if I’m in Europe. From what I understand, this isn’t a usual feature of a DNS server.
Is this a special feature of the DNS server? Do all nameservers support this sort of functionality?
