>This documents how I added IPv6 to my home network, which runs OpenBSD, using OpenBSD's ifconfig, slaacd, dhcp6leased, rad, and unbound. This should serve as a guide to other people in the same situation, but be aware you need to be running at least OpenBSD 7.6, as that is the version that added support for dhcp6leased and updated rad to handle DHCPv6 PD (prefix delegation). For older OpenBSD versions, you'll have to use ports, and there are multiple guides for that, use your friendly neighborhood search engine."
The author forgot Step 1. Ensure your ISP provides IPV6 services.
Otherwise, good documentation for the record.
