2.2.10 DHCPv6 Option Code 17 (0x0011) - Vendor Specific Information Option
A DHCPv6 client and server exchange vendor-specific information between themselves. This information is sent in the form of a vendor-specific information option, as specified in [RFC3315] section 22.17.
A Validating Server does not need to include a vendor class option (section 2.2.5) when authorizing itself using Rogue Detection.
