OVH gives you a IPv6 /64 block for dedicated servers but only /128 for a VPS and only allows buying extra IPv4 addresses.
I never previously had a reason to care much, but it turns out there are IP-based reputation services blacklisting based on /64 blocks as the smallest unit.

These folks block the entire OVH address space for "Level 3" and a bunch of the IP ranges for "Level 2":
uceprotect.net/en/rblcheck.ph
Check out the query they suggest for service providers:
uceprotect.net/en/rblcheck.ph
They want you to pay 249 Swiss Francs to get an IP range removed...

Alternatively, you can pay 25 Swiss Francs per month to have your IP added via whitelisted.org/?ip=51.222.140.
Nice business model. Clearly no conflicts of interest or extortion going on here. Email is such a terrible ecosystem. One of these services blacklisted us for requiring TLS.

Haha... I've run into these folks as well. Very trigger happy, too. They probably cause more problems that they allegedly solve...
