Still curious that the systems (IPv6 addresses) are changing too..  It's
not like it's the same route but just different rDNS results.  It's also
quite a bit of latency between and Comcast.  Also seeing ~20%
packet loss to systems in Comcast and ~15% packet loss end-to-end.
Certainly seems like there's something unhappy there, but I'll just keep
an eye on it.
