I am thinking of putting a esxi server in datawarehouse.
I just got one fysical network connection but I've got 2 ips address.

How can I bind these 2 ips addresses to the same interface?

    The ESXi server hosts multiple guest virtual servers.

    These guest virtual servers would each have an IP address and connect to the physical network card using a virtual switch.

    The host will have an IP for it's self to manage the host and a second network card for the virtual machines (could use one network card).

    Best Security Practice requires you to have 2 NICs minimum since its not recommended to share a NIC for managing the ESXi Host and for Virtual Machine Traffic even though its supported.

    yes but you have to configure esxi to have an ip address.
    Or Am I wrong?

    Yes ESXi will have its own IP address, and that is used for managing ESXi, and your hosts will then have their own IP addresses which all use the single NIC you have. But as kumarnirmal mentioned, you should not have ESXi Management and hosts going through the same NIC for security purposes.

    We have all management of our ESX servers going to a different NIC and a different IP range.

    As NICs do not cost that much money you should seriously consider having a second card.
