NETWORK CONFIGURATION
For background information on how the Notes Name Service works with name-resolver services such DNS, see the topic "Resolving server names to network addresses in NRPC" earlier in this chapter.
When you set up an IBM® Lotus® Notes® workstation on the TCP/IP network, you normally rely on DNS to resolve the name of the workstation's IBM® Lotus® Domino® home server the first time the workstation tries to connect to it. As long as the Notes workstation and Domino home server are in the same DNS domain level, DNS can accomplish the resolve.
When to edit the Net Address field in the Server document
The default format for a server's TCP/IP network address in Lotus Domino is its fully qualified domain name (FQDN) -- for example, app01.acme.com -- based on the DNS record and the IP address references in the system's TCP/IP stack. When a Notes workstation or Domino server requests this name, the TCP/IP resolver passes it to DNS, and DNS resolves the name directly to the IP address of the destination server, regardless of the DNS domain level of the requesting system.
If you do not want to enter the FQDN in the Net Address field, you can change it to the simple IP host name -- for example, app01 -- either during server setup or later by editing the Server document. For example, you might use the simple IP host name if you are setting up multiple TCP ports for NRPC, a configuration in which using the FQDN for each network address can cause connection failures if the Notes Name Service returns the FQDN for the wrong TCP port. In this case, using the simple IP host name ensures that DNS does a lookup in all domain levels within the scope of the domains defined in the requesting system's TCP/IP stack settings.
Caution In a production environment, do not use IP addresses in Net Address fields. Doing so can result in serious administrative complications if IP addresses change or if Network Address Translation (NAT) connections are used, as the values returned by the Notes Name Service will not be correct.
Secondary name servers To ensure that the Notes Name Service is always available over TCP/IP, when you set up a Notes user, you can designate a Domino secondary name server that stands in for the home server in these situations:
