Submitted On: 18 February 2010

Description: If 32-bit IP addresses are going to be legacy, why not release the “Class E” addresses? There’s no point in reserving them for future use.

ARIN does not manage the Class E address space and is not in a position to do as you suggest. The Internet Engineering Task Force (IETF) manages the addressing plan for the IPv4 address space and as such, any change would be determined by the IETF. Proposals similar to yours have been made in the past, but so far, there has been no agreement in the IETF to move forward with this idea.

Here are links to two of the more recent proposals:

It is possible that the authors of these documents are still interested in moving them forward, so you may want to contact them and see whether they plan to continue their work in this area.

In conclusion, your request is out of the scope of ARIN’s area of responsibility. Thank you for participating in the ARIN Suggestion Process. This suggestion is now considered closed.
