What bandwidth is needed for a busy DNS server?
What speed would I need for a DNS server that serves the public?

Naturally it would depend on how large the "public" is.
I would say 10mbs would be a minimum, as the actual DNS process takes minimal bandwidth and the DNS server also uses caching.
If that server is serving multiple roles naturally that bandwidth would also have to be considered.
Hope that helps.
