Definitely the latter one even with reverses.
I do usually add something like:

purgatory	A 195.64.92.136
purgatory	AAAA 3ffe:8114:2000:240:290:27ff:fe24:c19f
purgatory.ipv4	A 195.64.92.136
purgatory.ipv6	AAAA 3ffe:8114:2000:240:290:27ff:fe24:c19f

Reason: some programs can't be told to only use IPv6 or only IPv4
(usually -6 or -4 option).
This way one can 'force' it to use either transport.
I do usually leave out the ipv4 though as I don't use that much any more
anyways ;)

Greets,
 Jeroen
