Smm farm proxy ip inquire

Hi anyone know what kind of the proxy ip for the smm farm use?
e.g they offer one post 10k likes, if so, need 10k accs from over the world for it, so many accs with different countries’ ips. for mobile proxy, expensive and just several countries. for the residential ip, the cheap one is rotation. For the cost, can use the ipv6, but easy to get shadowban for the ipv6.
