DNS server software

[Claudio Lapidus <clapidus () gmail com>]

Hello all,

We are a mid-sized carrier (1.2M broadband subscribers) and we are looking
for an upgrade in our public DNS resolver infrastructure, so we are
interested in getting to know what are you guys using in your networks.
Mainly what kind/brand of software and which architecture did you use to
deploy it, and how did you do the sizing, all of it would be most helpful
information.

Many thanks in advance for your advice!
