IPv6 actually makes it easier to block spammy providers, because IPv6 address space is less fragmented. Digital Ocean (like most providers) has fewer, larger IPv6 blocks than they do IPv4 blocks: https://bgp.he.net/AS14061#_prefixes https://bgp.he.net/AS14061#_prefixes https://bgp.he.net/AS14061#_prefixes6 https://bgp.he.net/AS14061#_prefixes6 The overall number of IPv6 networks—despite containing many orders of magnitude more hosts—is fewer than under IPv4: https://bgp.he.net/report/prefixes https://bgp.he.net/report/prefixes This works out to not needing as many rules when you want to block traffic.
