This read-create value indicates how the IPv4 address being configured in this row was sourced, though this configuration table only defines assignedIp(1), meaning manually assigned. Admins encounter it as a fixed field confirming addresses entered through this table are always treated as manually assigned rather than dynamically obtained. For example, hh3cIpAddrSetSourceType always reads assignedIp(1) for any address an admin provisions through this table, distinguishing it from DHCP- or negotiation-derived addresses tracked elsewhere.
