Ok I think I see, you can host your own domain if you have a fixed 
ipaddress but if have ipaddress that changes need to register domain 
name and have company host it and advertise they know where it is but 
can change the nameservers for the domain from theirs to yours at 
changed ipaddress.
You can't willy nilly broadcast any domain to the internet yourself.
