What is the address of the servers that run the BlobVault and authd API? I am building a native Ripple Android wallet.

I understand that the BlobVault is currently centralized so what are the Ripple Labs server addresses that is safe to connect to those API servers - BlobVault and authd? 

Maybe my understanding is limited and I am asking the wrong question, but:

What is the address of the servers that run the BlobVault and authd API?

Thanks!
