Accessing the HDF Cloud Beta test through a proxy server

Just a lesson learned that might be useful for others accessing the Cloud Beta Test through a proxy server:

My proxy server can not categorize ip addresses, so I was unable to access the Beta Test through the ip address given and could not whitelist it on the proxy. I used ‘nslookup’ (on an internet connection not governed by the proxy) to discover the DNS name behind the ip address is http://ec2-[ip address given with dashes (-) not dots (.)] I was then able to whitelist that address.

Using[port number] as the endpoint in hsconfigure worked and I was able to connect to the ec2 instance.
