You should read the following slides for a discussion of how to use good
randomness for packet IDs without causing interop problems. The protocols
are TCP and IP, but similar considerations apply to DNS.

http://www.bsdcan.org/2006/papers/ImprovingTCPIP.pdf

Note that bad randomness will cause the same kinds of interop problems as
good randomness, so there's no harm recommending good randomness.
