Domain Mapping no working - redirecting to my IP.

Hi Guys,

I am trying to use the domain mapping plug in.

I think I have it set up properly in my main site. I seem to have done an ok job as the domain is arriving at http://www.darlingtonchristianfellowship.co.uk/cgi-sys/defaultwebpage.cgi. Which is part where domains go when routed to my server. But I can't map it, it keeps giving the result
in the attached pic.

Im just not sure what is going wrong.
