load balance DNS request

Question

I would appreciate some help creating an iRule on a DNS listener to point specific DNS request to an Internal Pool of DNS servers and send all others to an External Pool of DNS servers.&nbsp;
I created rule below which is not working.&nbsp;
when DNS_REQUEST {
if {
[DNS::name contains "company.com"] || [DNS::name contains "company.us"]
}
{pool Internal_DNS
}
else
{pool External_DNS}
}&nbsp;
Any assistance with this would be greatly appreciated.&nbsp;

Below was the solution.&nbsp;
when DNS_REQUEST {
if {
    [DNS::question name] ends_with "company.com" or [DNS::question name] ends_with "company.us"
    }
{pool Internal_DNS}
else
{pool External_DNS}
}&nbsp;
