address already used by other hosts in your network, including your Edge hosts.

11. (Optional) When you assign an Edge host to a node pool, if your Edge host has more than one NIC, you can optionally
specify which Network Interface Controller (NIC) the Edge host will use to communicate with the cluster. When you
select an Edge host, Palette displays a dropdown of all NICs present on the Edge host.

If the NIC is configured on the Edge host network, an IP address is displayed next to the name of the NIC. If the NIC is
not configured on the Edge host network, you can specify its IP address, default gateway, subnet mask, as well as DNS
server to configure it.
