[Bug] ipify's api6.ipify.org url

[sabbatum]

Description

Does the ipify url need to be changed to api64.ipify.org url? api6.ipify.org is now only for IPv6 requests. I can make PR if so.

Message from ipify.org

Oct 1, 2020 the A record for api6.ipify.org will be removed to make the subdomain only for IPv6 requests. For universal access please use api64.ipify.org.
