DNS-Server-IPv6-Address  AVP ( 169 )

This attribute contains the IPv6 address of a DNS server. This Attribute MAY be included multiple times in Access-Accept packets when the intention is for a NAS to announce more than one DNS server address to an RG/host. The Attribute MAY be used in an Access-Request packet as a hint by the NAS to the RADIUS server regarding the DNS IPv6 address, but the RADIUS server is not required to honor the hint.
