If they wanted to delay IPv6 then it would seem very strange that they
pushing for it's adoption.

Facebook/Amazon/Google/Twitter/Youtube are not the ones with the huge
blocks of IPv4 addresses. They didn't even exist when the large IPv4
blocks were allocated.

The organisations sitting on the large blocks of IPv4 are the old
"pre-dotcom" Internet companies, universities and gov/military:

Getting those people to give up IPv4 addresses is almost impossible.


The Google+others companies have a rapidly increasing need for IP
addresses and IPv4 addresses are a finite resource. Basic economics
will show you that is going to be a rising cost. To reduce it requires
moving the rest of Internet to IPv6. It's not enough to have IPv6
yourself, you have to get other people to use it.

The interests of "not-yet-even-a-sparkle-in-the-eye future major
Internet companies" are pretty much irrelevant. Bigger companies have
much more effective ways to deal with them than playing games with
IPv6, including legal battles over patent and other dirty tricks. But
I can't see any evidence that they are delaying IPv6.


You could make an more effective argument that large ISPs (such as BT)
have delayed IPv6 rollout, because of those reasons. BT have lots of
IPv4 address, and because they control the ADSL backbone they can stop
other ISPs that use their service from providing IPv6 addresses and so
force them to use private IP addresses.

I don't think that it is the main reason for BT were slow at providing
IPv6, especially after they took part in last year's world IPv6 day.
Management slugishness and the cost of replacement network kit are
more likely reasons.
