[RFCI-Discuss] wirralnews.com

[Derek J. Balling]

This is one of those cases where "if there were a bogusns zone, this  
would be listed"... the problem is that we can't chase down their  
authoritative NS set, because the NS's which are pointed to by the  
roots say (authoritatively) that there are no authoritative NSes...

$ dig @dpns1.dnsnameserver.org wirralnews.com. ns

; <<>> DiG 9.4.1 <<>> @dpns1.dnsnameserver.org wirralnews.com. ns

.... so when we go chasing down to form a list of "who should we ask  
about the MX record", the end result is a zero-length list
