GTM topology load balancing and anycast IP

How do people handle topology based load balancing with IP addresses such as 8.8.8.8 which are anycast to all corners of the world?

 

For example, I have a topology rule to send all Australian requests to an Australian DC. However, if people in Australia use 8.8.8.8 as their DNS server they will be sent to another DC as 8.8.8.8 is not in Australia according to geoiP.

 

Any thoughts?

    You should never get a request FROM an anycast address. Because you'd have no way to respond to it. Anycast is for sending a request TO.
