Examples of XorMappedAddress

de.fhkn.in.uce.stun.attribute.XorMappedAddress

Implementation of {@link Attribute} for the XOR-MAPPED-ADDRESS attributeaccording to RFC 5389. The IPv4 endpoint is encoded with the magic cookie of the STUN message header. The IPv6 endpoint is encoded with the magic cookie and the transaction id of the STUN message. The attributes is defined as follows:

 0                   1                   2                   3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |x x x x x x x x|    Family     |         X-Port                | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |                X-Address (Variable) +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
