Configuring IP Pools in vApps

IP pools provide a network identity to vApps. An IP pool is a network configuration that is assigned to a network used by a vApp. The vApp can then leverage vCenter Server to automatically provide an IP configuration to its virtual machines.

Specify an IP Address Range

You can set up an IP address range by specifying a host address range within a network. IP pool ranges are configured with IPv4 and IPv6. vCenter Server uses these ranges to dynamically allocate IP addresses to virtual machines when a vApp is set up to use transient IP allocation.

Procedure

1. In the inventory, select the datacenter that contains the vApp.

2. In the IP Pools tab, right-click the IP pool that you want to edit and select Properties.

If no IP pools appear, click Add to add a new IP pool.

6. (Optional) Enter a comma-separated list of host address ranges in the Ranges field.

A range consists of an IP address, a pound sign (#), and a number indicating the length of the range. The gateway and the ranges must be within the subnet, but must exclude the gateway address. For example, 10.20.60.4#10, 10.20.61.0#2 indicates that the IPv4 addresses can range from 10.20.60.4 to 10.209.60.13 and 10.20.61.0 to 10.20.61.1.

2. Click OK.

Select DHCP

You can specify that an IPv4 or IPv6 DHCP server is available on the network.

Procedure

1. In the inventory, select the datacenter that contains the vApp you are configuring.

2. In the IP Pools tab, right-click the IP pool that you want to edit and select Properties.

If no IP pools appear, click Add to add a new IP pool.

3. In the Properties dialog box, select the DHCP tab.

4. Select either the IPv4 DHCP Present or IPv6 DHCP Present check box to indicate that one of the DHCP servers is available on this network.

Specify DNS Settings

Enter the DNS settings for the vApp.

Procedure

1. In the inventory, select the datacenter that contains the vApp you are configuring.

2. In the IP Pools tab, right-click the IP pool that you want to edit and select Properties.

3. If no IP pools appear, click Add to add a new IP pool.

In the Properties dialog box, select the DNS tab.

4. Enter the DNS server information.

Specify the servers by IP addresses separated by a comma, semicolon, or space.

You can enter the following types of DNS information:

a. DNS Domain

b. Host Prefix

c. DNS Search Path

d. IPv4 DNS Servers

e. IPv6 DNS Servers

Specify a Proxy Server

Specify a HTTP proxy server for the vApp.

Procedure

1. In the inventory, select the datacenter that contains the vApp.

2. In the IP Pools tab, right-click the IP pool that you want to edit and select Properties.

    If no IP pools appear, click Add to add a new IP pool.

3. In the Properties dialog box, select the Proxy tab.

4. Enter the server name and port number for the proxy server.

The server name can optionally include a colon and a port number.

For example, web-proxy:3912 is a valid proxy server.

Select Network Associations

You can associate one or more networks with an IP pool.

Procedure

1. In the inventory, select the datacenter that contains the vApp.

2. In the IP Pools tab, right-click the IP pool that you want to edit and select Properties.

If no IP pools appear, click Add to add a new IP pool.

3. In the Properties dialog box, select the Associations tab.

4. Select the networks that use this IP pool.

A network can be associated with one IP pool at a time.
