2.2.36 DN_ALTERNATE_ADDRESS (IPv6)
The DN_ALTERNATE_ADDRESS (IPv6) structure is described in detail under the DN_ALTERNATE_ADDRESS (IPv4) (section 2.2.35) structure.
The following diagram represents the contents of the structure when it contains an IPv6 alternative address. The DN_ALTERNATE_ADDRESS (IPv4) (section 2.2.35) structure demonstrates the contents of the same structure when it contains an IPv4 alternative address.
