   option-code:      OPTION_IAPREFIX (26) 

   option-length:    25 + length of IAprefix-options field 

   preferred-lifetime: The recommended preferred lifetime for the IPv6
                     prefix in the option, expressed in units of
                     seconds.  A value of 0xFFFFFFFF represents
                     infinity. 

   valid-lifetime:   The valid lifetime for the IPv6 prefix in the
                     option, expressed in units of seconds.  A value of
                     0xFFFFFFFF represents infinity. 

   prefix-length:    Length for this prefix in bits 

   IPv6-prefix:      An IPv6 prefix 

   IAprefix-options: Options associated with this prefix
