So what about all the organisations that were assigned class A address blocks? Should they not do something and give up these classes, come 2011? We certainly don't have 2^32 devices out there.
- zokier 16y agoBecause I hate downvoting without explanation: This question arises every time when exhaustion of IPv4 is discussed. Reallocating class A blocks would only delay the inevitable by few months (less than a year for sure).
- maxklein 16y agoAre 50% of all IPv4 addresses not class A? Can you explain a bit more in-depth why it would not make a significant difference?
- wmf 16y agoTalking about "class A" is a red herring. There are used addresses and unused addresses. It's not clear how many allocated-but-unused addresses exist because the audits necessary to find them would be expensive, but people have made estimates and those estimates are not that large. At any rate, the transfer market should flush out some of these "dark" addresses once they are needed.
- ianburrell 16y ago50% of IPv4 addresses were in class A (0-127). But only 40 of the blocks were assigned to organizations in legacy assignments.
- wmf 16y agoOrganizations with unused addresses will start selling them soon. https://www.arin.net/resources/transfer_listing/ https://www.arin.net/resources/transfer_listing/
