DNWithOctetString and DN-Binary
all appear to point to 126.96.36.199
as a DN Syntax
DNWithOctetString (also referred to as DNWithBinary) is defined in an Internet Draft draft-armijo-ldap-syntax-00 for Microsoft Active Directory LDAPSyntaxes with an OID of 1.2.840.1135188.8.131.523
Encoded as a :
DNWithOctetString = OctetTag ':' Count ':' OctetString ':' DN
OctetTag = 'B' | 'b'
Count = positive decimal number, counting number of encoded characters
OctetString = [EncodedByte]* // Note: the number of characters in the
string encoding of the OctetString is Count.
EncodedByte = [0-9 | a-f | A-F] [0-9 | a-f | A-F]
DN = <normal string encoding of a DN>
As an example, the string encoding of the combination of 0x74 0x65 0x73
0x74 and DC=Microsoft,DC=Com is
184.108.40.206 for a DN with binary (a.k.a. DN with octetString) or A Distinguished Name plus a binary large object.
