All the nameservers through the internet have to update, Once that is done then you have the domain, You can't have it instant its impossible there is billions of miles of cable for the internet, unfortunally the internet is not that fast yet!!!

48 hours is an estimate 100,000 odd domains get registered every day more that that estimate even, It depends what time they were registered, when the US is off the web you will find it will probarly come on faster heck I got a new .co.cc and it hasntt come on yet and that was yesterday

My knowledge of DNS is not very great.
Thanks for your sharing.

The actual main wait comes from the propagation of the DNS through caches. There are only a few dozen main DNS servers worldwide that actually share updated DNS data with eachother. The rest just cache what those few say. Basically if you look up a domain it can send a response through a number of DNS servers until it reaches one that knows about the domain. Once the request is fulfilled, the request filters back through all the DNS servers it went through to get there and caches the data on those servers so if anybody else looks up the same domain name rather than stepping up through the servers in the same process it will just come to first one that has seen that domain pass through in the last 6-12 hours and use the data that the original connection did. The disadvantage of this is that alot of these caches remain for 6-12 hours. By the time data filters through all the caches it can take up to 48 hours to get it. Sometimes it can be almost immediate. It just depends on your luck and how popular the domain is.
"...the GPLv2 in no way limits your use of the software. If you're a mad scientist, you can use GPLv2'd software for your evil plans to take over the world ("Sharks with lasers on their heads!!"), and the GPLv2 just says that you have to give source code back. And that's OK by me. I like sharks with lasers. I just want the mad scientists of the world to pay me back in kind. I made source code available to them, they have to make their changes to it available to me. After that, they can fry me with their shark-mounted lasers all they want."

Nice post twiste, yeah his right about different name servers just cacheing info

Incidentally, it wouldn't be that much strain on the servers to make the caching go faster. If DNS were redesigned, it'd definitely be feasible to get DNS to update in, say, a few minutes. But DNS was designed badly, and no one really feels like updating it.

And the money to do it, I suppose it could cost billions.
