For the record, the reason the randomization is a weakness in DNS
protocol:

http://linuxsysadminblog.com/2008/12/how-to-check-if-your-dns-server-implements-source-port-randomization/

or

In the core policy, I see djbdns having the very same macro.
Surprisingly, bind does not have it (or I missed it).
