I need a lesson in DNS. Again! I knew I was going a step too far.
Still, I'll keep on making mistakes. e.g. maybe the IP address was also moved with the hosting as a whole..? I've never hosted a website (whod've thought!?) but perhaps you' could check your records etc but that's something else to possibly consider/ignore. lol
I'll keep posting these options as I make them up...

But I'm off to a (BNI) business meeting now so it'll be at least a few hours before my next foray into the 'so,-you-think-you're-making-an-intelligent-guess,-do-you?' zone!
Nice.
