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.
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.

- 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.
      - Ensuring DNS resolves on Windows™ systems -- All TCP protocols
        If an IBM® Domino® server is a Microsoft™ Windows™ system, often two name services exist on the system -- NetBIOS over IP and DNS.
      - Ensuring DNS resolves in NRPC -- Best practices
        The following procedures provide the best name-resolution practices for anIBM® Domino® server using the default NRPC configuration on a TCP/IP network (oneIBM Notes® network port for TCP/IP). These procedures address the following DNS configurations – one DNS domain and multiple DNS domain levels
      - Ensuring DNS resolves in NRPC -- Alternative practices
        These procedures provide alternative name-resolution practices for an IBM® Domino® server using the default NRPC configuration on a TCP/IP network (one Notes® network port for TCP/IP).
      - Ensuring DNS resolves in NRPC
        This practice ensures good DNS resolves in NRPC for companies with multiple DNS domain levels.
    - 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.
  - 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
    Use the references listed here to plan for, install, upgrade to, and configure the IBM® Notes® client.
  - Planning security
    An important aspect of planning security for your Domino® environment is understanding the tasks and features involved with securing each type of resource.
- Configuring
  Use this information to configure an IBM® Domino® network, users, servers (including Web servers), directory services, security, messaging, widgets and live text, and server clusters. Also use this information to set up IBM iNotes® on a server using Domino Off-Line Services (DOLS).
- Securing
  This section describes IBM® Domino® security features, including execution control lists, IDs, and SSL.
- Administering

- Tuning
  Use this information to improve IBM® Domino® server, Domino Web server, and messaging performance through the use of resource balancing and activity trends, Server.Load commands, advanced database properties, cluster statistics, and the Server Health Monitor.
- Troubleshooting
  This section describes how to find and solve problems with IBM® Domino® server and Administrator client.

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.

Consider the DNS configuration, as well as the effect of other protocol name-resolver services, when you choose the format for the common name of the Domino® server.

Note that these procedures listed the Related topics apply only to servers handling communications between IBM® Notes® and Domino® (NRPC services). If you administer servers that provide Internet services such as HTTP, SMTP, POP3, or LDAP, you can skip these topics, as these services use DNS directly.

Note: When you choose a common name for a Domino® server that uses DNS, use only the characters 0 through 9, A through Z, and the dash (-). Do not use spaces or underscores.

Note: The DNS names held in Notes® and Domino® are not case sensitive; Notes® workstations and Domino® servers always pass DNS names to DNS in lowercase.
