If you find the answer from one of these, please let us know by solving the thread!

Go to project setting and scroll down to see the "Private Networking" section

Under Network settings

Actually i cant find the IPv6 there.

is this how i can do taht ?

const port = process.env.PORT || 3000; app.listen(port, "::", () => { console.logServer listening on [::]${port}); });

Hey, according to the docs, your shown snippet is the correct way to listen on IPv4 and IPv6 for express.

you can check using "railway ssh" and then run "ps aux". Any AI will tell you if it listens on IP6.

that code gave me only the port ??

i need the full IPv6 ... could u plz tell me how ?

Hey, you already use :: in your code and it binds to IPv4 and IPv6.

I am telling you that code print me the port only.not the full ip address

Hey, you should reference your service using service variables and not hard code the IP address. You can see how this is done here https://docs.railway.com/guides/private-networking#using-reference-variables.

Hi Now i could get my IPv6. we tried to whitelist this IP in the API service but still we cant communicate with the api. what is the problem ?

Hey, could you please elaborate on how you are whitelisting the IPv6 address? A workaround would be to use a secret for authentication that only your API and the service that is using it should know.
