The "autoconf" keyword uses SLAAC for IPv6 configuration, it does not
uses DHCP.  OpenBSD's DHCP is for IPv4 only.  Your ISP should be able
to tell you if they use SLAAC or DHCPv6, and if the latter, you'll
need to install and provision one of the DHCP servers that supports
DHCPv6, such as perhaps isc-dhcp-server or kea.
