    IPv4 has long stopped being a simple technical identifier system. It has become a constrained, priced, and operationally embedded infrastructure asset class. “In the IPv4 market, execution is not paperwork. Execution is continuity under registry-layer uncertainty.”https://heng.lu/on-why-i-lease-exis

    IPv4 Poverty Penalty: Why Small Networks Pay More

    IPv4 access can look equal on paper. The same registry forms.The same transfer rules.The same provider contracts.The same compliance language.The same renewal process. But equal paperwork does not always create equal outcomes. For large operators, IPv4 friction may be manageable. They may have legal
