The NETCONF statement type represented by "±-rw address* [ip]" is a 'list'. In YANG, which is the data modeling language used by NETCONF, a 'list' statement defines a sequence of list entries. Each entry is like a row in a table. The "+" indicates that this is a configuration data node, "rw" means read-write, and the asterisk (*) signifies that multiple address entries are allowed (hence it's a list), with "ip" being the key for each unique entry in the list.
