Specify DNS Server for dnslookup

[salem34]

Hi Ninjas

Im aware that you can resolve ips & hosts with the built in dnslookup like

<search> | lookup dnslookup clientip as dst OUTPUT clienthost as DST_RESOLVED

But is there a way to specify the DNS Server to resolve the ips? I think by default i takes the default dns entry of the splunk machine and i would like to specify another one (without touching the command script).

Any ideas?

I found this link in splunk answers ...however when I tried to use it threw python exception.
