Greetings unbounders, I occasionally need to look up an A record for which one of the authoritative nameservers is lame: mail.opusnet.com Unbound seems to accept the referral from the lame nameserver as final, rather than trying the others: $ ping mail.opusnet.com ping: Cannot resolve "mail.opusnet.com" (No address associated with name) Is that intentional? Maybe I'm misunderstanding the behavior. Thanks, Richard.
