Hello Maddy123,

With the question posed, it leaves me a little worried that no-one planned the creation of the servers very well. Are the people asking this wanting to:-
  • add the details to the /etc/hosts file on the server in question?
  • add the details to the /etc/hosts file on all the unix servers? (and equivalent on windows servers)
  • add the details to a DNS server?
I'm concerned that the planning should have been done in advance for something as fundamental as server name and IP address resolution. How did you get to where you are? Were these toy servers built by application developers who now want them put to a production use?


The preference for converting 'server name --> IP address' and 'IP address --> server name' would be with a DNS server (or a few for resilience) That way, one update is reflected to all servers so if things change you don't have the risks associated with multiple updates being required, i.e. errors, forgotten servers, sequence of update, which process has last save etc.


Perhaps with a little more context, we can help you more than you are asking.

NAME
localemanager -- Configure OpenDirectory Server Locales SYNOPSIS
localemanager operation [-l localename] [-subnet 1.2.3.4/5] [-server servername] [-i IP address] DESCRIPTION
localemanager creates, destroys, and edits OpenDirectory Server Locale information. Locales are collections of OpenDirectory servers to assist clients in locating the nearest OpenDirectory Server. To use OpenDirectory Server Locales, simply create a locale on an OD server with the createLocale operation. Then add servers and subnets to the locale. All localemanager operations are performed on the local OpenDirectory node. The first time a locale is created, a DefaultLocale will automatically be created as well. The DefaultLocale will be used for any clients that don't match a subnet in any other locale. Before a locale can be configured, the server must already be an OpenDirectory server. Locales can be defined on each of the OD servers or on a single OD server in the group of OD master/replicas. For the latter, the locale information will get replicated to all of the other servers but locales will need to be "enabled" on the other servers by running the command localemanager enableLocales. Commands: help Displays the commands and options. createLocale Creates a new locale on the local OD server. This command requires the -l option. deleteLocale Deletes a locale from the local OD server. This command requires the -l option. showLocale Displays the current locale(s). The -l option can be used to display a specific locale. If -l is not specified, all locales are displayed. enableLocales Enables the use of locales on an OD server. This command is automatically run the first time any localemanager command is run on an OD server. Therefore this command only needs to be run if no other localemanager commands have been (or will be) run on this server. addSubnet Adds a new subnet to the specified locale. This command requires the -l -subnet options. removeSubnet Removes a subnet from the specified locale. This command requires -l -subnet options. addServer Adds a server to the specified locale. This command requires the -l -server options. If the -i option is specified, that IP address will be used by locale clients. This may be useful for multi-homed servers to restrict locale clients to a specific network interface. If the -i option is not specified the IP address(es) will be looked up. removeServer Removes a server from the specified locale. This command requires -l -server options. If the -i option is specified, only that IP address will be removed from the locale. If the -i option is no specified, all of the server's IP addresses will be removed from the locale. Options: -l locale Locale name. -subnet 192.168.0.0/16 Subnet specified in CIDR notation. -server server.example.com Server fully-qualified domain name. -i 192.168.1.1 Use this IP address for the server. Typically used to limit locale clients to a specific interface on a multi-homed server. FILES
