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.

I think the “THING” that people are starting to worry about is how to deploy a network when you can’t get IPv4 space 
for it at a reasonable price.

Greg, 

After investigating what a previous poster said about Cisco and Juniper, I'm getting the feeling that not all major 
impediments to running MPLS over IPv6-only networks have been addressed. 

Your comment mentions LDP IPv6 support. Do you now handle all the major gaps identified the the IETF MPLS IPv6 Gap 
Analysis (RFC7439) from this last January? 

https://tools.ietf.org/html/rfc7439#section-3 

It seems like their are still gaps in the MPLS spec itself before IPv6 has parity with IPv4 in MPLS. 

The LDPv6 support is just the control plane portion to get labels 
assigned to IPv6 addresses. This should get you basic forwarding of 
encapsulation and forwarding of IPv6 traffic in MPLS. The immediate 
use-case would be removal of IPv6 BGP routing in the core, if that is 
your thing. 

Otherwise, yes, there are still a bunch of MPLS gaps that need to be 
fixed for those additional services to run natively over an IPv6-only 
network. Baby steps... 

Mark.
