To override the default IP selection logic, you can create a hint file that includes the `NODEIP_HINT` variable to override the default IP selection logic. Creating a hint file allows you to select a specific node IP address from the interface in the subnet of the IP address specified in the `NODEIP_HINT` variable.

For example, if a node has two interfaces, `eth0` with an address of `10.0.0.10/24`, and `eth1` with an address of `192.0.2.5/24`, and the default route points to `eth0` (`10.0.0.10`),the node IP address would normally use the `10.0.0.10` IP address.

Users can configure the `NODEIP_HINT` variable to point at a known IP in the subnet, for example, a subnet gateway such as `192.0.2.1` so that the other subnet, `192.0.2.0/24`, is selected. As a result, the `192.0.2.5` IP address on `eth1` is used for the node.
