PLANNING
Domino® servers and partitioned Domino servers can have multiple NICs (network interface cards), each with its own IP address.
A single HCL Domino server can have multiple IP addresses if you use multiple NICs that each offer 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.
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 accomplish the following tasks:
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:
Ensuring DNS resolves in advanced TCP/IP configurations When you have HCL Domino servers with multipleHCL Notes network ports for TCP/IP, follow these procedures to ensure server name-to-address resolution by DNS.
