Yes. Given that this is running on loopback, it doesn't matter if the 
service is running on either the v4 or v6 loopback address. Unless a 
system running this service has absolutely no v4 at all (it doesn't even 
need to be offering v4 service to customers), the v4 loopback address is 
sufficient.

There seems to be wide disagreement about what is the v6 loopback 
address: some of these addresses exist on some v6 systems but not 
others, or so we were told. If there is a v6 loopback address that is 
universally deployed (as 127/8 is for v4), we can add it, although it 
won't actually make this more deployable.
