A working IP address is required for ESXi to be fully operational. To configure basic network settings, use the vSphere Client or the direct console.

Use the vSphere Client in the following cases:

You are satisfied with the DHCP IP address.

You are allowed to use the DHCP IP address temporarily. In this case, connect to this address with the vSphere Client. Then use the vSphere Client to configure any networking changes.

Use the direct console in the following cases:

You are not satisfied with the DHCP IP address.

You are not allowed to use the DHCP IP address.

ESXi does not have an IP address. This could happen if the autoconfiguration phase did not succeed in configuring DHCP.

The wrong network adapter was autoselected during autoconfiguration phase.
