Essentially labor (support) costs: Training support staff on IPv6, including helping customers provision/use IPv6. Adding IPv6 to internally developed databases and provisioning tools. Adding support to IPAM and our address-allocation and tracking tools to support IPv6 (we are largely statically addressed to the customer for historical reasons). Configuring IPv6 across the network. Troubleshooting/supporting two protocols that can break instead of one.
Many of these have become less expensive than before. For example, 10 years ago, I would have added "upgrade all the gear that doesn't support IPv6," but I think we're mostly beyond that.
