No Business Case For IPv6, Survey Finds

alphadogg writes "Business incentives are completely lacking today for upgrading to IPv6, the next generation Internet protocol, according to a survey of network operators conducted by the Internet Society (ISOC). In a new report, ISOC says that ISPs, enterprises and network equipment vendors report that there are 'no concrete business drivers for IPv6.' However, survey respondents said customer demand for IPv6 is on the rise and that they are planning or deploying IPv6 because they feel it is the next major development in the evolution of the Internet."

Try running multiple servers on multiple machines behind the same NAT, where one would like them to be accessible to the outside world via default port numbers.

To be fair, you can use a reverse proxy for this.

*IF* for some reason that didn't involve how many IP's you actually have available, you still wanted to utilize NAT for some reason, you still could do that with ipv6... no problem at all.

You can, but people were told for ages they couldn't. That's actually a big factor opposing IPv6's adoption.

Lots of smart, but idealistic IPv6 designers considered private networks harmful, and wanted to eliminate them from IPv6. They thought that by saying "no, there's no support for private networks, and you don't need them anyway", people would start making addresses public again.

They were right, but saying that wasn't very smart. RFC1918-style networks are safety blankets for network administrators, and when the IPv6 people threatened to take them away, they were terrified. Instead of moving to IPv6 and making their networks publicly-numbered, administrators stayed with IPv4. It's a classic case of perfect being the enemy of good.

Finally, in 2005, the IPv6 people realized the value of pragmatism and set aside reserved addresses with RFC4193. However, the delay and initial opposition to private networking has retarded IPv6 adoption by several years, at least.

18+% of IPv4 addresses unused

To quote myself from a post I made on another site:

According to IANA, of the 256 /8 IPv4 blocks, there are 31 Unallocated blocks and 16 Reserved for Future Use. Those 47 blocks means that approximately 18.36% of the IPv4 space is currently sitting empty. That's not even counting the the 16 /8 blocks reserved for Multicast, the 127/8 block reserved for a single IP (127.0.0.1), or counting any unallocated blocks in the CIDR networks.

Anyone who says we're running out of IPv4 addresses needs to go back and look at what is actually allocated and what isn't. Since nearly 20% of the IPv4 space is currently empty, I can't see how they can make the claim that we're running out of addresses with a straight face.
