Planning the TCP/IP network
The default TCP/IP configuration for an IBM® Domino® server is one IP address that is globally bound, meaning that the server listens for connections at the IP addresses of all NICs on the computer. Global binding works as long as the computer does not have more than one IP address offering a service over the same assigned TCP port.
Advanced Domino® TCP/IP configurations
Domino® servers and partitioned Domino servers can have multiple NICs (network interface cards), each with its own IP address.
Partitioned Domino® servers and IP addresses
When you set up an IBM® Domino® partitioned server, it is usually best to assign a separate IP address to each partition and use a separate NIC for each. Using a separate NIC for each address can make the computer's I/O much faster.

- What's new in IBM® Domino® 10?
  Learn about all of the new features for administrators in IBM® Domino® 10.
- Overview
  Welcome to IBM® Domino® Administrator Help.
- Installing
  Use this documentation to install the IBM® Domino® server and subsequently deploy the IBM Notes® client.
- Planning
  Use this topic as an overview of planning task.
  - Roadmap for deploying Domino® servers
    Use this as a tool when planning how to integrate IBM® Domino® into your existing environment.
  - Planning server-to-server connections
    Servers must connect to each other to exchange data, for example to replicate databases and exchange mail. You can create connections between servers across a local area network (LAN) or wide area network (WAN), by using a pass-through server (a server that acts as an intermediary server between a client and its destination), or over the Internet. Create a Server Connection document whenever you need to establish any new or additional server connections. You can modify this document when necessary.
  - Planning directory services
    IBM® Domino® provides a range of directory service features.
  - Planning a mail routing topology
    IBM® Domino® offers you considerable flexibility in configuring your mail system infrastructure, allowing you to use IBM Notes® routing, SMTP routing, or both, for internal and external messages.
  - Planning a cluster
    When planning a cluster, it is important to consider the performance and ability of your hardware. The cluster must have enough CPU power, memory, and disk space to handle the cluster traffic and the number of databases and replicas required.
  - Planning the TCP/IP network
    The default TCP/IP configuration for an IBM® Domino® server is one IP address that is globally bound, meaning that the server listens for connections at the IP addresses of all NICs on the computer. Global binding works as long as the computer does not have more than one IP address offering a service over the same assigned TCP port.
    - Using Domino® on IBM® i with TCP/IP
      The IBM® Domino® server on IBM i uses TCP/IP to communicate with IBM Notes® clients and the Internet. For the Domino server to work properly, TCP/IP must be set up and active on your system.
    - NRPC name-to-address resolution over TCP/IP
      In the TCP/IP protocol, the method most commonly used to resolve server names to network addresses is the Domain Name System (DNS), an Internet directory service developed both to allow local administrators to create and manage the records that resolve server names to IP addresses and to make those records available globally. While the POP3, IMAP, LDAP, and HTTP services use DNS directly, the NRPC service uses a combination of the Notes® Name Service and DNS to resolve server names to network addresses.
    - Ensuring DNS resolves in TCP protocols
      When you register a new IBM® Domino® server, you specify a common name for it. Within a Domino hierarchical name, the common name is the portion before the leftmost slash. For example, in the name App01/East/Renovations, the common name is App01. The common name, not the hierarchical name, is the name that the Domino server is known by in DNS.
    - Considerations for changing a server IP address
      Changing the IP address of an IBM® Domino® server can cause access issues.
    - IPv6 and Domino®
      You can enable IPv6 support in IBM® Domino® for SMTP, POP3, IMAP, LDAP, and HTTP services on IBM AIX®, IBM i, and Linux™ systems.
    - Advanced Domino® TCP/IP configurations
      Domino® servers and partitioned Domino servers can have multiple NICs (network interface cards), each with its own IP address.
      - Partitioned Domino® servers and IP addresses
        When you set up an IBM® Domino® partitioned server, it is usually best to assign a separate IP address to each partition and use a separate NIC for each. Using a separate NIC for each address can make the computer's I/O much faster.
      - Ensuring DNS resolves in advanced TCP/IP configurations
        When you have IBM® Domino® servers with multipleIBM Notes® network ports for TCP/IP, follow these procedures to ensure server name-to-address resolution by DNS.
  - Planning the NetBIOS network
    The IBM® Domino® network is compatible with NetBIOS, a set of IBM session-layer LAN services that has evolved into a standard interface that applications use to access transport-layer network protocols.
  - Messaging overview
    The IBM® Domino® mail system has three basic components: Domino mail servers, Domino mail files, and mail clients. The Domino mail server is the backbone of an organization's messaging infrastructure, acting both as an Internet mail server and an IBM Notes® mail server. Domino provides standards-based Internet messaging through its support of the Simple Mail Transfer Protocol (SMTP), Post Office Protocol version 3 (POP3), Internet Message Access Protocol (IMAP), and Multipurpose Internet Mail Extensions (MIME). At the same time, Domino supports Notes mail through the use of Notes routing protocols -- Notes remote procedure calls (NRPC) -- and the Notes rich text message format.
  - Planning your Notes® client deployment

Partitioned Domino® servers and IP addresses

When you set up an IBM® Domino® partitioned server, it is usually best to assign a separate IP address to each partition and use a separate NIC for each. Using a separate NIC for each address can make the computer's I/O much faster.

Domino® is designed to listen for TCP/IP connections on all NICs in a computer system. If more than one partition is hosting the same service (NRPC, SMTP, POP3, IMAP, LDAP, or HTTP), fine-tune which partitions listen for which connections by associating each service's TCP port with a specific IP address.

As an alternative to using a separate NIC for each IP address, you can use a single NIC and still assign a separate IP address to each partition.

If you are unable to assign a separate IP address to each partition, you can use port mapping.

Note: As an alternative to port mapping, you can use port address translation (PAT), in which a firewall redirects the TCP port connection to a different TCP port. Both port mapping and PAT require advanced skills to implement correctly.
