Protocol to Internet

To select an Internet protocol, use the down arrow on the entry field and select one. The selected protocol determines what version of IP addresses the HMC uses for connections to your service provider.

The value you select here must reflect the internet protocol used by your installation. Most installations use Internet Protocol Version 4 in which addresses appear in the format representing the four bytes of the IPv4 address, separated by periods (for example, 9.60.12.123) to access the internet. If you are unsure of the internet protocol used by your installation, contact your network administrator.

Note: If an SSL proxy is used to access the internet, the protocol selected here must reflect the internet protocol used by the SSL proxy to connect to the internet. It may differ from the protocol used by the HMC to connect to the SSL proxy.
IPv4
Internet Protocol version 4 only. This is the default.
IPv6
Internet Protocol version 6 only.
IPv6 and IPv4
The Hardware Management Console will first attempt to connect to the service provider using Internet Protocol version 6. If this fails, Internet Protocol version 4 is attempted. This selection provides redundancy in case a version of IP addresses temporarily fail.
