Load balancer for Bind

[Frank Pikelner]

Hello Bert,

This is the first I've heard of DNSDIST. I'll need to read more about it, but wanted to ask whether upon receiving the query, does DNSDIST act as a bridge for the complete request/response, or simply redirects the traffic with the response bypassing DNSDIST?

THanks,

Frank

Hi Francesco,

dnsdist can transfer the original IP over EDNS Client Subnet (ECS).
http://dnsdist.org/README/ has how this works.

I don't know if BIND can make use of the original IP address though.
PowerDNS geoipbackend can in any case. BIND is also an excellent choice.

Good luck!
