As with all good things in life, there is always another option... I guess
giving Cisco your data is about as good as giving Google your query data

resolver[1234].opendns.com all appear to be local via EquinixIX and rather
fast! They don't publish an AAAA records on the aforementioned names but
some old notes that suggest 2620:0:cc[cd]::2 are goers....
