Load balancing is done at the authoritative DNS level.
Users of authoritative DNS are recursive DNS servers.
Users that connect to and generate traffic to your datacenters might share recursive DNS servers, and some recursive DNS servers serve more users than others.
www.domain.com 126.96.36.199 (Weight 2)
www.domain.com 188.8.131.52 (Weight 2)
That means that 184.108.40.206 will be given to 2 out of 4 recursive DNS servers and that 220.127.116.11 will be given to 2 out of 4 recursive DNS servers.
That does not mean that traffic to 18.104.22.168 and 22.214.171.124 will be even as not all recursive DNS servers have the same number of end users.
So the traffic to your site may not match the weights you have set at the DNS level.
