The recommended setup is to use static IP addresses for the service console of an ESX host. You can set up the service console to use DHCP, if your DNS server can map the service console’s host name to the dynamically generated IP address.

If your DNS server cannot map the host’s name to its DHCP-generated IP address, you must determine the service console's numeric IP address. Another caution against using DHCP is that the numeric IP address might change as DHCP leases run out or when the system is rebooted.

VMware does not recommend using DHCP for the service console unless your DNS server can handle the host name translation.
