DNS (Score 1)

I didn't have time to read everyone's post here but the one thing I think everyone is forgetting or overlooking is why cache was created/used in the first place. 1st. Could you imagine the amount of extra traffic on the internet and core devices if every lookup had to traverse the net? It was designed because there is no need to change you DNS RRs constantly they should be static, or failing that only needed to be update once in a while. 2nd. what happens if my DNS serves go down (yes assuming both of them go) I can assume that at least some people can still find my service based on cached results from ISPs or root servers. Contrary to what I just said I also agree that the internet backbone is huge and could handle the extra traffic and maybe it is time to rethink old policy. just because its worked in the past dose not mean we have to continue to use it for the future. A lot has change since the first inception of the DNS RFC.
