There are two levels which do cycling. The comm internal on it's own array of DNS results for the connected-to host, and the forwarding loop over connection attempts to its own copy of whatever the current cycled-to address is. You may have just uncovered the bug. If it's not even trying most of the addresses that could account for the v4 ones being skipped. Amos
