PBN Hosting - IPv6 ?

my pbn is currently hosted on multiple shared hosts. as the network grows bigger, it's getting difficult to manage so i was thinking to move all the sites to one host and get a dedicated ip for each.
and then i found out about IPv6 addresses - would this be safe, i mean to host each site on a different ipv6? and also are there hosts that let you buy a bunch of ipv6?

Imo the shared hosting method works best right now. I don't recommend moving all sites to one host.
