addrobj
Specifies an identifier for the unique IP address or set of addresses that is used in the system. The addresses can be either IPv4 or IPv6 types.
The identifier uses the format: interface / user_specified_string.
The interface refers to the IP interface to which the address is assigned. The interface variable must reflect the name of the datalink on which the IP interface is configured.
user-specified-string refers to a string of alphanumeric characters that begins with an alphabet letter and has a maximum length of 32 characters. Subsequently, you can refer to the addrobj instead of the numeric IP address when you use any ipadm subcommand that manages addresses in the system, such as ipadm show-addr, or ipadm delete-addr.
