Summary

In order to force the migration from IPv4 to IPv6, it is suggested that large users of IPv4 blocks return a percentage of the blocks they have been assigned; this way, large users could catalyze the migration from IPv4 to IPv6. It is also suggested to set a date to completely discontinue the use of the Internet protocol.

Rationale (Describe the problem you intend to solve)

If the end of IPv4 were to be set for 2030, i.e., 15 years from now, it is very unlikely that equipment would still be in operation – very few devices would still really require IPv4, as starting in 2031 all communications via IPv4 would be suspended. Thus, each year these large networks would return 1/15 of their assigned IPv4 addresses, which could then be reassigned to those who still needed them, remaining valid until 2030.

As for the equipment, many devices may not even be of use anymore due to hardware capacity issues, they will likely be missing security updates, possibly legacy devices very close to – or past – the end of their service life, as new devices already support native IPv6.

Current text

The proposal seeks to define a date for the programmed termination of IPv4, such as 2030.

It also proposes that large users return the blocks they have been assigned in order to promote migration to IPv6. In order to calculate the rate with which addresses would be returned, for example, 15 years remain until 2031, so these large users should return their blocks at a rate of 1/15 per year.

After the scheduled termination of IPv4 in 2030, starting in 2031, communications would occur only via IPv6.
