Before implementing EE, carefully consider your business requirements, especially the following questions:

• Identify your preferences; will you need dynamic or predefined connections?
• Evaluate your priorities. Which of the following considerations is most important in your environment?
  • Less maintenance
  • Less definition
  • More control
  • More security
• Do you want to use host names or IP addresses for IP configuration? Do you maintain a DNS to resolve host names to IP addresses? The benefit of maintaining your own DNS is that you can keep all IP addresses in a central location. If the IP addressing scheme changes, you do not have to update VTAM® definitions because DNS resolves the host names to the correct IP addresses.
• Decide whether you want to use EE connection network and which EE partner nodes will participate in the EE connection network.
• Determine whether network address translation (NAT) is being used in your IP network. See Network address translation (NAT) considerations for more information related to using host names.
