Wildcard DNS setup

Hi

I'm sorry to bother you, but please could I ask which is the correct method for setup of a Wildcard DNS for a domain, and I have posted here in case it should work on both methods.

These intructions work for me

These instructions do not work for me

The latter is the way that I would have thought a wildcard DNS was setup but in reality, all it does is to display the siteworx account domain which is first in order.

Many thanks

John
