Here's an example reverse record for IPv6 address
0.2.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.2.8.0.184.108.40.206.220.127.116.11.18.104.22.168.ip6.arpa. 3600 IN PTR sinclair.wpi.edu.
DHCPv6 is supported by ISC DHCP. You have to run a separate service
(dhcpd -6) since the server only supports one protocol at a time.
However, DHCPv6 isn't required to assign v6 addresses. DHCPv6 is only
really required if you want control over the assignments such as in a
managed network environment. You can instead use SLAAC (Stateless
Address Auto-Configuration). This is automatic--no server required.
You can run radvd on the router to announce the availablility of the
router and global prefix(es) available on the link.
yum install radvd
