Aussie ISP gets eye-watering IPv4 bill, shifts to IPv6

[Edit: I was wrong about that: //No, it is not. By default the suffix is generated based on your MAC address.//]

Moreover the wasteful norm to rely on /64 subnets and other, similar more practical than privacy-conscious design decisions diminish the potential to stay pseudo-anonymous.

I don't think MAC is the default [1]:

the following operating systems use IPv6 privacy extensions BY DEFAULT:

    All versions of Windows after Windows XP
    All versions of Mac OS X from 10.7 onward
    All versions of iOS since iOS 4.3
    All versions of Android since 4.0 (ICS)
    Some versions of Linux (and for others it can be easily configured)

For routers, then I have no way to tell. But I would be surprised if stateless addressing wasn't the default on the vast majority of retail routers.
