Meeting in Prague

Hi Chris,

We have a new tech report that some may find interesting:


Title: Recursives in the Wild: Engineering Authoritative DNS Servers

Abstract: In Internet Domain Name System (DNS),
  services operate \emph{authoritative} name servers
  that individuals query through \emph{recursive resolvers}.
Operators strive to provide reliability
  by operating multiple name servers (NS), each on a separate IP address,
  and by using IP anycast to allow NSes to provide service from many
physical locations.
To meet their goals of minimizing latency and balancing load across NSes
and anycast,
  operators need to know how recursive resolvers select an NS,
  and how that interacts with their NS deployments.
Prior work has shown some recursives search for low latency,
  while others pick an NS at random or round robin,
  but did not examine how prevalent each choice was.
This paper provides the first analysis of how recursives select between
name servers in the wild,
  and from that we provide guidance to name server operators to reach
their goals.
  We conclude that all NSes need to be equally strong and therefore we
recommend to deploy IP anycast at every single authoritative.
