RFC 5061:
This is an opaque integer assigned by the sender to identify each
request parameter. The receiver of the ASCONF Chunk will copy this
32-bit value into the ASCONF Response Correlation ID field of the
ASCONF-ACK response parameter. The sender of the ASCONF can use this
same value in the ASCONF-ACK to find which request the response is
for. Note that the receiver MUST NOT change this 32-bit value.
Address Parameter: TLV
This field contains an IPv4 or IPv6 address parameter, as described
in Section 3.3.2.1 of [RFC4960].
ASCONF chunk with Error Cause Indication Parameter (Unresolvable Address)
should be sent if the Delete IP Address is not part of the association.

(ESTABLISHED) (ESTABLISHED)
