A couple of months ago voted for IPv4 by paying $1/month for every IPv4 IP address on my new server. 128 IP addresses total. That is well over $1k/year voting

A couple of months ago voted for IPv4 by paying $1/month for every IPv4 IP address on my new server. 128 IP addresses total. That is well over $1k/year voting power. The reason for that purchase is that IPv4 addresses represent internet reputation while crawling websites. I am not interested in getting IPv6 at all. How much did you pay for IPv6?
