Hi Falko,
Its
www.f-football.co.uk
This is being rerouted from 123-reg.co.uk where I purchased my domain name from, so i setup the DNS as you said with @ CNAME writables.servehttp.com and www CNAME writables.servehttp.com
The writables.servehttp.com is from NOIP.com that points to my dynamic ip.
Thanks
Steve
