Cypherpunk owns IPv4 addresses across the /18 and /19 subnets. The subnets are leased out to customers that operate in the privacy and cybersecurity domain – most notably VPN providers. Despite the gradual adoption of IPv6, innovations including Network Address Translation (NAT) and network layer virtualization architectures have continued to enhance the value proposition of IPv4 as a co-existential protocol to an emerging IPv6.
