loadbalance

Name

loadbalance - acts as a round-robin DNS loadbalancer by randomizing the order of A and AAAA records in the answer.

Description

See Wikipedia about the pros and cons on this setup. It will take care to sort any CNAMEs before any address records, because some stub resolver implementations (like glibc) are particular about that.

Syntax

loadbalance [POLICY]

POLICY is how to balance, the default is "round_robin"

Examples

Load balance replies coming back from Google Public DNS:

. {
    loadbalance round_robin
    proxy . 8.8.8.8 8.8.4.4
}
