Connecting from a Notes client using IPv6 address-NRPC: Use this procedure to connect from the
Notes client to a server using an IPv6 address.
1. Choose File -- Database -- Open.
2. In the Server field, enter the IPv6 address. Optionally, you can enter a server name that resolves to an
IPv6 address instead of entering the IPv6 address in the Server field.
A low-priority Connection document is added to your local Domino Directory (NAMES.NSF).
Advanced Domino TCP/IP configurations
A single 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:
v Split the client load for better performance
v Split client-to-server access from server-to-server communication
v Set up mail routing, replication, or cluster replication on an alternate path (private network)
v Partition a Domino server so that more than one partition offers the same Internet service (SMTP,
POP3, IMAP, LDAP, or HTTP).
v Allow access to the Domino server via a TCP/IP firewall system over a different network segment, a
configuration known as a demilitarized zone (DMZ)
v Use a Domino passthru server as an application proxy
v Provide network/server failover, used in mission-critical resource access
v Set up alternate window and/or maximum transmission unit (MTU) settings for satellite uplink and
downlink connections isolated from local access connections
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″ later in this chapter.
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:
v Isolating local versus WAN Notes named networks so local users can see only local Domino servers
v Preventing independent remote access dialup connections (ISDN dialup router) from being arbitrarily
accessed
v When setting up redundant WAN path connections for server to server access
v When the use of a different TCP/IP port map is needed for firewall connections
v When offering HTTP services to a different group than NRPC connections
v As a service provider when offering Domino server access for either Notes or Web clients to different
groups/companies
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.
