DNS round robin adalah teknik load balancing sederhana di mana beberapa [[a-record|record A]] atau [[aaaa-record|record AAAA]] dengan [[ip-address|alamat IP]] berbeda dikaitkan dengan satu hostname. [[recursive-dns|Resolver]] bergiliran melalui alamat secara berurutan, mendistribusikan koneksi masuk ke beberapa server. Karena round robin mengandalkan pengacakan di tingkat DNS daripada kesadaran sesi, tidak ada pemeriksaan kesehatan atau sesi sticky; server yang gagal terus menerima lalu lintas sampai record diperbarui secara manual atau [[ttl|TTL]] kedaluwarsa. Alternatif yang lebih canggih termasuk routing Anycast, GeoDNS, dan load balancer lapisan aplikasi.
Contoh
A website with three servers at 1.2.3.4, 1.2.3.5, and 1.2.3.6 can list all three as A records for www.example.com; successive DNS lookups return them in rotation, spreading traffic roughly evenly across all three servers.
