Dual stack IPv6 for IPv4 depletion

Wed Jul 8 20:10:55 UTC 2015

Tell a start-up ISP it'll be $10k - $25k for PI IPs and they'll laugh in your face.

Owen, 

Paying for IPv4 space definitely raises the capital requirements for any new provider startup. It's not so bad right now, when deals are plentiful in the $10k to $20k range for /24s. But when a /24 hits $100K, bootstrapping a new ISP will be impossible.
