How to get kubernetes host IP from inside of a pod?

Let's say we have a frontend and a backend pods running in a kubernetes cluster.

Both pods have corresponding services exposing them on the host (type: NodePort). In the end, the frontend uses <Host IP>:<Port 1>, and the backend runs on <Host IP>:<Port 2>.

How to find out the host IP so that it could be used in the frontend pod (to be defined as a value of a variable)? Tried with setting localhost, but it didn't work, so probably the exact IP has to be defined.
