...

Vendor-Specific_Option_Code (1 byte): This MUST be 0xDF.

Vendor-Specific_Option_Length (1 byte):  If nonzero, the value is calculated as (N*16 + 1) bytes, where N is the number of IPv6 remediation-server addresses. An option length of zero also indicates zero IPv6 remediation server addresses.

Number_of_IPv6_Remediation_Server_Addresses (1 byte): The number of NAP IPv6 remediation server addresses.

Vendor-Specific_Option_Data (variable): IPv6 addresses of NAP remediation servers in network byte order.
