x-fapi-customer-ip-address should probably have an example for ipv6
Issue #294 resolved
Some UK banks apparently reject requests where
x-fapi-customer-ip-address contains an IPv6 address. Just for clarity, we should add an IPv6 example in the spec.
( https://gitlab.com/openid/conformance-suite/-/issues/761 has been opened to consider adding checks for this in the conformance suite.)
With IPv4 being deprecated, the IPv6 example should probably come before the IPv4 example.
I added an example in FAPI 2 Baseline in this branch: https://bitbucket.org/openid/fapi/branch/danielfett/fapi2/advanced
