Well, it is at least minimally related to ordering in that it insists on the qname being first in Answer. I'd like to hear what software out there is requiring this though. Is it a/some library stub(s)? For sure I've written test software that generated packets but which didn't implement compression at all. But I also didn't execute them in a widely diverse environment, or probably even had such answers interpreted by glibc. _______________________________________________ DNSOP mailing list -- [email protected] To unsubscribe send an email to [email protected]
