Reducing load on root servers. Been doing this for many years by running local copy of root.zone and making judicious use of HOSTS and local authoritative nameservers. I have a localhost caching resolver but I rarely need to use it. I wrote my own non-recursive stub resolver which is faster. Unlike the majority of ICANN DNS users I am not mindlessly querying the same servers for the same records day after day. And I am certainly not querying remote root servers like the ones mentioned in this blog post. I am storing the addresses I need permanently and updating them periodically if they change. Guess what? Most addresses do not change. It is likely that few if any users are doing what I am doing and as such, there an enormous amount of gratuitous DNS traffic on the internet. I can safely say I am not contributing to that. A smarter way? Yes, I think it is.
