Nothing. In the enterprise world the benefits vs the negatives of implanting ipv6 is not there. I manage around 3500 devices, 7 buildings and have 2 ten gig wan connections and one 4 gig wan connection and use NAT along with about 26 public ipv4 addresses.

To this day I have no compelling reason to adopt ipv6. Dual stack setup adds unnecessary traffic and complexity for little advantage.

To this day it is still hard to get assigned a block of static ipv6 addresses, have applied twice and been denied.

So not only is there little upside it is also still hard to even get allocated a block.

“Step 1: Verify You Qualify If you meet any of the criteria below, you qualify to receive IPv6 address space:

Have an IPv4 assignment from ARIN or one of its predecessors Intend to immediately be IPv6 multi-homed Have 13 end sites (offices, data centers, etc.) within one year Use 2,000 IPv6 addresses within one year Use 200 /64 subnets within one year“
