You can limit the use of an ID to a selected host or hosts by assigning host names to IDs. Use the options in the Host Mappings dialog box to map multiple IP addresses or DNS names to a single host name. Then, in the ID Properties dialog box, assign the host name to specific IDs.
By assigning host names to IDs, you can create a single configuration or session that provides access to multiple environments and multiple hosts, and a single named pool with all the IDs used by all the hosts, but still control which IDs are used to access which hosts.
With UTS sessions, users can connect to multiple hosts from a single session by issuing a $$OPEN command to access a different environment. For other session types, you must create a separate session configuration for each host but you can use the host mapping feature to ensure that an ID is used only once with a particular host, even if the host has multiple IPs.

|If you delete a host name, all of the IDs that use that name are updated automatically so that they can be used with any host. If an ID is in use when you make the change, it continues to use the host name until it is released.|
