With anycast DNS, is it the IP or the FQDN that is doing it?

  • 772

i am somewhat new to anycast and i want to know if it works on the IP or the FQDN. The reason i ask is, i have a anycastDNS account with a provider. And i would like to use my own domain name to make it whitelabel. So i could use a CNAME record to point to their nameservers but that would result in 2 DNS lookups. Or could i just create an A record and point it to the IP address, that nameserver record is pointing to? By pointing that A record do i defeat the while anycast feature?

    anycast is on the "ip level"

    It pretty much has multiple providers broadcasting to the internet saying the IP is here and its up to the routers between the client and servers to decide which is the quickest location to the endpoint.

    also a CNAME if its within the same zone file is a single lookup
