I know that domain names are constantly changing, and I know there are a lot of them, but there is clearly a region of the domain name space which is stable. How would I go about getting a list, even a very big one?

Such a thing must logically exist, even if it is in a distributed form, because the web's DNS servers resolve names to IP addresses. So in theory if I could poll all the DNS servers in the world at a moment in time I would have the complete list of mapped names. Is there a practical way of doing that?

As an aside, does anyone have any good estimates of how many domain names exist at the moment?
