Iquery connection with translation address

Hi All,

I need some help to understand the iquery connection to translation address . For example 

Address : 1.1.1.1

Transalation address 2.2.2.2

F5 will initiate the traffic to 1.1.1.1 or 2.2.2.2 , As my understanding F5 device initiate the traffic to 1.1.1.1 to establish the iquery.

But on the device i could see F5 initiate the traffic to translation address.

is there any document to refer which destination iquery mesh will connect when translation address.
