The dns entries do seem to be sorted (somewhere). nslookup shows them in whatever order they appear, but the mIRC /dns command displays them sorted. I guess that is why my server is getting such a large portion of the network load.

It seems to me that mIRC used to display them in a rotating fashion (as nslookup does). I can't remember which version appeared to do it that way, but if Khaled says mIRC doesn't sort the entries, maybe the way mIRC queries winsock has changed, or maybe M$ has made some update to winsock.
