Fixing IP parsing.  Should fix issue 20.

Not entirely sure why this was there: 
 address = address.value if address

If that line should just be removed,  I can remove it and re-issue.    I left it in - in case I am missing a usage of it.   But in my vCloud it always fails. 

Let me know if you'd like a complete XML resopnse on my vapp endpoint and I can share that for you to test with. 

Thanks for writing this API!
