Using Internet SSL to connect to remote support

All the communications are handled through TCP sockets initiated by the HMC and use a high-grade
SSL to encrypt the data that is transmitted. The destination TCP/IP addresses are published (see "Internet
SSL address lists") so that external firewalls can be configured to allow these connections.
Note: The standard HTTPS port 443 is used for all communications.
The HMC can be enabled to connect directly to the Internet or to connect indirectly from a proxy server
provided by the customer. The decision about which of these approaches works best for your installation
depends on the security and networking requirements of your enterprise. The HMC (directly or through
the SSL proxy) uses the following addresses when it is configured to use Internet SSL connectivity.

Choosing an Internet Protocol

Determine the IP address version used when the HMC connects to your service provider.
Most users use Internet Protocol Version 4 (IPv4) to connect to a service provider. IPv4 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. You can also use Internet Protocol Version 6 (IPv6) to connect to a
service provider. IPv6 is often used by network administrators to ensure unique address space. If you are
unsure of the Internet Protocol used by your installation, contact your network administrator. For more
information about using each version, see "Setting the IPv4 address" on page 55 and "Setting the IPv6
address" on page 56.
