Hi Bryn...
That's just one of the DNS server numbers (10.0.0.138)...You also need an alternate one as well....From memory Telstra do list both of these...
If it isn't there try these...(just pick your state)
DNS Numbers 
(this is a very small thumbnail) lol...
With step 10 it means the numbers you see on your screen, not what's written in the instructions, they're just an example...
erkaninho would you be able to start a new thread of your own as if I help you with yours as well in this thread it will get to confusing...
Just supply these details in your new thread...
