Aspera transfers use one TCP port for session initialization and control, and one UDP port for data transfer. The TCP port is usually either 22 (default port for SSH) or 33001, and the UDP port is by default 33001. The IP address of our Aspera instance is currently 188.8.131.52. However, that could change at any time. If you ever suspect the IP to have changed, simply ping v2.disneyabc.tv and (at least with the current architecture) the IP you get back should be the one.
