ipv6 limit on instagram registration

Hi ,
So i've been testing a registration bot in the past afew days and i haven't had much success using ipv6 addresses to bypass their system . It's not even 1acc/ip . It blocks the whole /48 range .
Is it really a good idea to use ipv6 to this kind of bot ? Or i should go back to ipv4 ?
Thank

i think instagram api calls for creating account don't allow ipv6.
there must be other bots.. ipv4 proxies can be used to create 3 accounts per day i believe. (could be wrong about that number)
