 - [sceNetCtlGetInfoV6](../../../core/libs/prx/libSceNetCtl/Export.cpp) (libSceNetCtl, NID `Jy1EO5GdlcM`) - imported by PPSA08587. `(int code, SceNetCtlInfoV6* info)` with codes 1-5 (IP address, link-local address, default route, primary and secondary DNS) comes only from [SharpProspero](https://github.com/SvenGDK/SharpProspero), whose source is unknown; shadPS4 and fpPS4 only stub it. A null `info` answers `INVALID_ADDR`, a code outside 1-5 `INVALID_CODE`, and a host without an IPv6 address `NOT_CONNECTED`, as `sceNetCtlGetStateV6` reports it. The layout of each answer is unverified, so every code throws on a host with an IPv6 address
 - [sceNetCtlGetResult](../../../core/libs/prx/libSceNetCtl/Export.cpp) (libSceNetCtl) - `(int eventType, int* errorCode)` reports no error: event types 1-3 (disconnected to IP obtained, the numbering `sceNetCtlCheckCallback` delivers) write 0 to `errorCode`, as `sceNetCtlGetResultV6` does. The error code a console reports for each event, a disconnection's cause in particular, is unconfirmed. Callers found: PPSA20052 (Worms Armageddon: Anniversary Edition 01.003.000) calls it 2 s into boot, and PPSA24191 (Monster Hunter Wilds) without a network, with event 1 (disconnected) as its first call. A null `errorCode` answers `INVALID_ADDR` and other event types throw, as their error code on a console is unknown
 - [sceNetCtlGetResultV6](../../../core/libs/prx/libSceNetCtl/Export.cpp) (libSceNetCtl, NID `H5yARg37U5g`) - `(int eventType, int* errorCode)` comes only from [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Net/NetCtl.cs#L246-L251), whose source is unknown; shadPS4 only stubs it. Callbacks registered with `sceNetCtlRegisterCallbackV6` receive no event, so event types 1-3 write 0 to `errorCode`; what a console writes before the first event is unmeasured. A null `errorCode` answers `INVALID_ADDR`, as `sceNetCtlGetResult` does, and other event types throw, as their error code on a console is unknown
+- [sceNetCtlRegisterCallbackForNpToolkit, sceNetCtlUnregisterCallbackForNpToolkit, sceNetCtlCheckCallbackForNpToolkit](../../../core/libs/prx/libSceNetCtl/Export.cpp) (libSceNetCtl) - a table of eight callbacks apart from the IPv4 and IPv6 ones, with the `(int eventType, void* arg)` callback, follows [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/main/src/core/libraries/network/net_ctl_obj.h), whose NpToolkit check delivers the same events to that table. The three share the register, unregister and dispatch of `sceNetCtlRegisterCallback`, `sceNetCtlUnregisterCallback` and `sceNetCtlCheckCallback`, so they return the same initialization, address, slot-limit and ID errors, and the check reports the state `sceNetCtlCheckCallback` does. Whether the console keeps this table apart, and what `sceNetCtlCheckCallback` does with it, is unverified on hardware
 - [ApRp exports](../../../core/libs/prx/libSceNetCtl/Export.cpp) are constant-success functions in the supplied native module and consume no arguments. No callers were found in the supplied system-library decompilations, so unused callback, output and configuration argument types remain unresolved. Protected stub bodies are unchanged.
