Abstract:

The Domain Name System (DNS) leverages nearly 1K distributed servers to provide information about the root of the Internet's namespace. The large size and broad distribution of the root nameserver infrastructure has a number of benefits, including providing robustness, low delays to topologically close root servers and a way to cope with the immense torrent of queries destined for the root nameservers. While the root nameserver service operates well, it represents a large community investment. Due to this large cost, in this paper we take the position that DNS' root nameservers should be eliminated. Instead, recursive resolvers should use a local copy of the root zone file instead of consulting root nameservers. This paper considers the pros and cons of this alternate approach.
