Some cells may want/need to broadcast both the private and public
addresses for their servers if the cell is located behind a NAT.

The interesting output would be the list of cells which are doing
so.  It is possible that not everyone realizes that they are publishing
private addresses.

This is simply an indication that the AFS client has been given the
IP address of a file server and the client is checking periodically
to see if that file server is currently available.
