How about… $ dig +noall +answer mail.automatedwastesystems.net in a | egrep 'IN\tA\t' | cut -f6 which correctly returns nothing in this case, but when there’s a CNAME chain ending in addresses it returns them $ dig +noall +answer dave.knig.ht in a | egrep 'IN\tA\t' | cut -f6 216.235.14.46 and surely you want IPv6 support… $ dig +noall +answer dave.knig.ht in a dave.knig.ht in aaaa | egrep 'IN\t(A|AAAA)\t' | cut -f6 216.235.14.46 2001:4900:1:393::2 dave
