Ensuring DNS resolves in advanced TCP/IP configurations
Using Domino on IBM i with TCP/IP
The HCL Domino server on IBM i uses TCP/IP to communicate with HCL 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 HCL 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.
Considerations for changing a server IP address
Changing the IP address of an HCL Domino server can cause access issues.
IPv6 and Domino
You can enable IPv6 support in HCL 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.
