Windows 2008 dns cannot resolve it.

BIND can.

Hi Joe,

Does Windows 2008 like anything in the "hosting" TLD?

I notice that the nameresolve.com servers returning the CNAME to
kissimmee-fl.vts.hosting are also returning an SOA record for
"hosting" in the authority section which looks very strange to me.
Perhaps Windows is rejecting it as an invalid, possibly dangerous
response packet?

Regards,
Bill Herrin



I think that provided SOA record is a "local" or "alternate" version and its existence is why the nxdomain response is being sent to the windows dns server that accepts it at face value (but does not appear to store it in cache, so this is not precisely cache poisoning)

Here is another example, unrelated to the new TLD's
