**How severe does this issue affect your experience of using Ray?** - High: It blocks me to complete my task. Need to change the default address. Integrating with another application as a plugin has its own scheduler using rays default address. This causes ray workers/actors to be canceled/killed before processing is complete. ---

You can set the OS environment variable RAY\_ADDRESS to override the `ray.init()` address. ---

Thanks I will give that a try. ---

Alas it does not seem to work. Is it just the IP address or is IP Address:PORT that should be expressed. If port should be added what is the default? ```auto File "D:\apps\vec\formatters\ATAKRadar.py", line 20, os.environ["RAY_ADDRESS"] = "127.0.1.1" File "D:\apps\vec\ingestors\converter_ATAKRadar.py", line 33, in __init__ ray.init(local_mode=False, ignore_reinit_error=True, _temp_dir=ray_session_path) File "d:\venv\lib\site-packages\ray\_private\client_mode_hook.py", line 105, in wrapper return func(*args, **kwargs) File "d:\venv\lib\site-packages\ray\worker.py", line 975, in init connect_only=True) File "d:\venv\lib\site-packages\ray\node.py", line 166, in __init__ self.validate_ip_port(self.address) File "d:\venv\lib\site-packages\ray\node.py", line 302, in validate_ip_port _ = int(port) ValueError: invalid literal for int() with base 10: '127.0.1.1' ``` Thanks ---

I added a port number, so that exception above goes away. Now I get warning and the code will not function. ```auto 2022-03-21 12:18:51,604 WARNING node.py:1466 -- Unable to connect to GCS at 127.0.1.1:14000. Check that (1) Ray GCS with matching version started successfully at the specified address, and (2) there is no firewall setting preventing access. ``` At this point I do not see a way to use just **RAY\_ADDRESS** to change the default address it is using. When I allow both the DASK scheduler to use the same address my code does work however there is a performance penalty. ---

Hmm I think I misunderstood your original question. `RAY_ADDRESS` is used to specify the address that the Ray driver/client should connect to, but it assumes that there is already a Ray instance running there. Try using `ray start --head --port ` to start a Ray instance, then you can connect to it with `ray.init(address="auto")`. ---

Currently the ray app is embedded as a package and not separate instance that is running. ---

Hmm not sure I understand the issue you’re running into. Are you just using `ray.init()` to start Ray? This should choose a random port, so I’m not sure how you’re getting a port conflict. What version of Ray are you using? ---

Running version 1.11.0 and yes running ray.init() on initialization of the Class instance that other app invokes. ---

Just need ability to have it use a different IP address than 127.0.0.1 when you run with ray.init().
