No, fallback to TCP relies on receiving a truncated UDP response. You
never want a DNS client to be waiting around for a response that will
not arrive.

Rockall, Malin: So
Dear, I have to balance two DNS servers for a special reason.
I need your comments please:
1) If I use HAProxy for DNS load balancing, this software only works with
TCP protocol (not UDP). The DNS clients are a mix of Windows, Cisco and
Linux machines, so I think they ask for a FQDN using UDP

If you want failover, I recommend L3 switch like linux ipvs or similar.

Description: OpenPGP digital signature
DNS-Racing is a method of load balancing access to servers which are
multi homed and provides lowest latency access to users and network
resilience to ISP/routing failure.
*
**What does it do?*
It permits a server which is connected to two ISPs to use the optimal
ISP when transferring data
order
I set by adding rrset-order option to the configuration file.
Do you have a clue what could be the problem?
Is it possible that the light weight resolver doesn’t
support load balancing in lwres mode?
Thanks,
Nati

A long time ago it used to be in turn, but all current versions of BIND

I have the forwarders statement to fwd queries to a few DNS servers on my
LAN.
forwarders { 10.0.0.1;

The bind documentation says that these fwders are queried "in turn", but
what exactly does that mean? I understand it to mean tha
