I think your post is not related to this forum and I hope, sooner or later, it will be move to an appropriate forum like General Computing or sthing...
But I will try to answer your question... If you have a domain name, you have to set your static IP adress of your host in the domain name control panel so that everyone launching that domain name will be redirected to the real host... If you try to contact the domain name provider, it's more likely that you will get a proper way to deal with mapping your host and yoru domain name... Hope it helps..
