Hi all,

>From the manual of PowerDNS Recursor, learned the following settings can be
used in its config file:

forward-zones Comma separated list of ’zonename=IP’ pairs. Queries for
zones listed here will be forwarded to the IP address listed. Since version
3.1.5, multiple IP addresses can be specified. Additionally, port numbers
other than 53 can be configured.
Sample syntax: forward-zones=example.org=;,

I just want to know the mechanism when we use multiple ip for Query a
zone.  I mean is this process sequel or  parallel?  When we using multiple
ip for resoving a specific domain-name, which answer given by the
forwarders should be picked up by PowerDNS Recursor and then return it to
user's client program?

Any hints on this issue will be highly appreciated.
