A network protocol profile contains a pool of IPv4 and IPv6 addresses for use by vApps. When you create a network protocol profile, you set up its IPv6 configuration.

You can configure network protocol profile ranges for IPv4, IPv6, or both.vCenter Server uses these ranges to dynamically allocate IP addresses to virtual machines when a vApp is set up to use transient IP allocation.


  1. Enter the IP Subnet and Gateway in their respective fields.
  2. Select DHCP Present to indicate that the DHCP server is available on this network.
  3. Enter the DNS server information.
    Specify the servers by IP addresses separated by a comma, semicolon, or space.
  4. Select the Enable IP Pool check box to specify an IP pool range.
  5. If you enable IP Pools, enter a comma-separated list of host address ranges in the IP pool range field.
    A range consists of an IP address, a pound sign (#), and a number indicating the length of the range. For example, assume that you specify the following IP pool range:


    Then the addresses are in this range:

    fe80:0:0:0:2bff:fe59:5a:2b - fe80:0:0:0:2bff:fe59:5a:34


    fe80:0:0:0:2bff:fe59:5f:b1 - fe80:0:0:0:2bff:fe59:5f:b2

    The gateway and the ranges must be within the subnet. The ranges that you enter in the IP pool range field cannot include the gateway address.
