inet_interfaces takes 'all' or a list of IP addresses. It will also
take hostnames but such configuration is fragile; however if you do
have hostnames 'ipv6' and 'ipv6' then the above would do something.
For the remainder of this response I assume that you mean inet_protocols
which takes all, ipv4, and/or ipv6.

inet_protocols makes no difference. The inet_interfaces value is
converted into a bitmask that does not depend on the order of all,
ipv4, and/or ipv6.
inet_protocols=ipv4 converts into 1 (2<<0)
inet_protocols=ipv6 converts into 2 (2<<1)
inet_protocols=all converts into 3 (2<<0 + 2<<1)
inet_protocols=ipv4,ipv6 converts into 3 (2<<0 + 2<<1)
inet_protocols=ipv6,ipv4 converts into 3 (2<<0 + 2<<1)
inet_protocols=all,ipv4,ipv6 converts into 3 (2<<0 + 2<<1)
inet_protocols=all,ipv6,ipv4 converts into 3 (2<<0 + 2<<1)
and so on for other permutations of the same.
