It's good thing to at least resolve the DNS for link prefetch, so a new check 
might encourage other vendors to consider this much safer improvement

I couldn't make any of my tests with DNS prefetching work in Internet Explorer 
9 on Windows 7 (IE update version 9.0.3, version 9.0.8112.16421).

I tried explicit prefetching via the link tag and different attribute value 
combinations. Neither rel="prefetch", nor rel="dns-prefetch" worked. Neither 
href="absolute_url", nor href="//hostname" worked. I tried by opening a local 
html file and by opening remotely the same file uploaded on my server in 
Internet. I also tried if it would work when the domain name was added to 
"Trusted sites". It didn't.
Prefetching while typing in the address bar failed too.

Wireshark showed no sign of DNS activity during all tests (except for resolving 
the domain of my server in the remote test, of course).

Am I doing something wrong or forgetting something?

Greetings, Radko dinev
Any ideas?
