// 1. plan 9 never used a static source port for queries, Using dynamic ports is better than static, but if they're sequential (or otherwise predictable), it doesn't buy you all that much.
// 2. who does recursive queries on external interfaces? I've been traveling in companies and countries with restricted local DNSs, but open routes to home. Or open enough to get DNS through; sometimes not VPN, ssh, or functional equivalent (to say nothing of 9p). Being able to query an unrestricted DNS was wonderful. I've also worked for companies who had folks working from home pointing their home computers at work DNS (and some other services) over the public internet. I'd probably grant that it's a security problem, but it wasn't an "error" in the normal sense. Anthony
