you're not recommending dnscache, you are recommending against it. but really you are spreading FUD. a) what various ways are you referring to?
I don't have a boatload of specifics but one that bugs me is incomplete TCP support. You can only do an SOA/AXFR sequence over TCP.
b) I'm not sure what the distribution is, but it sure looks round-robin...
I'm not familiar with the dnsip program, but it is from djbdns, and appears to be doing it's round robin-ing internally, or... randomizing the output more likely. Specifically version 1.05 of dnscache definitely does not round robin, if you query multiple times in succession with dig, or host, you will get the same answer every time. Perhaps that was finally corrected. If you ask a BIND or basically anything else (not sure of others specifically) you get round robin results. While I tend to somewhat agree that the clients should randomize or round-robin internally, the fact is most don't.

I would recommend dnscache before the OP had a problem BTW. // George -- George Georgalis, systems architect, administrator <IXOYE>< -- To UNSUBSCRIBE, email to debian-isp-REQUEST@lists.debian.org with a subject of "unsubscribe".
