Yi, If you go to this page https://labs.ripe.net/statistics/?tags=ipv4 and scroll all the way to the bottom, you will see the number of remaining IPv4 addresses. If you click on the title of the graph, you wil see another pge with more information about the RIPE NCC's available IPv4 address pool. Please let us know if you have any more questions.
