"An alternate method of load balancing, which does not require a dedicated software or hardware node, is called round robin DNS. In this technique, multiple IP addresses are associated with a single domain name; clients are given IP in round robin fashion. IP is assigned to clients for a time quantum."
https://en.wikipedia.org/wiki/Load_balancing_(computing)#Round-robin_DNS
"DNS load balancing relies on the fact that most clients use the first IP address they receive for a domain. In most Linux distributions, DNS by default sends the list of IP addresses in a different order each time it responds to a new client, using the round-robin method. As a result, different clients direct their requests to different servers, effectively distributing the load across the server group."

CERTO.
Segundo Kurose(2014,p.96),"O DNS provê alguns outros serviços importantes além da tradução de nomes de hospedeiro para endereços IP:
- Apelidos (aliasing) de hospedeiro;
- Apelidos de servidor de correio;
- Distribuição de carga: O DNS também é usado para realizar distribuição de carga entre servidores replicados, tais como servidores web replicados."
