NETWORK CONFIGURATION

Advanced Domino TCP/IP configurations
A single IBM® Lotus® Domino™ server can have multiple IP addresses if you use multiple NICs, each offering an address, or if one NIC offers multiple addresses. Having multiple IP addresses allows the server to listen for connections at more than one instance of the TCP port assigned to NRPC (1352) or at TCP ports that are assigned to other services such as LDAP or HTTP. Both individual Domino servers and partitioned Domino servers can have multiple NICs, each with its own IP address.

Multiple IP addresses and NICs on a Domino server
Set up a Domino server with multiple IP addresses, each with its own NIC, if you want to:


For a configuration with multiple IP addresses, you must bind each listening port to the appropriate IP address to ensure that each TCP service receives the network connections intended for it.

For more information, see the topics Binding an NRPC port to an IP address and Binding an Internet service to an IP address. For more information on private networks for cluster replication, see Determining whether to create a private LAN for your cluster.

Note A configuration with multiple NICs does not increase the number of Domino sessions you can have on a server. In TCP/IP, machine capacity depends on processors and memory.

Multiple IP addresses with one NIC
Reasons to use one NIC to serve multiple IP addresses include:


For a configuration with multiple addresses and one NIC, you must configure the TCP/IP stack and bind each listening port to an IP address.
