  ## Additional Information

  * Depends on #6626

  * Depends on #6635

  * Depends on #6636

  * Dependency for #6629

  * The `simplifiedmns_merkleroots` test constructs 15 `CSimplifiedMNListEntry` elements and populates them with a `CService`. So far, since we allowed direct assignment of the `CService` without validation, no checks were made to see if they would pass validation but if we start enforcing validation rules _when setting values_, two problems emerge.

    * Using non-default ports on mainnet (`BasicTestingSetup` is mainnet by default, [source](https://github.com/dashpay/dash/blob/bcd14b05cec7d94986f114ca17bbdadbee701d9b/src/test/util/setup_common.h#L100)), this has been resolved by using `RegTestingSetup` (which is based on regtest) instead.

    * As the index is used to generate the address, starting from 0, the first address is `0.0.0.0`, which is not a valid `CService` address ([source](https://github.com/dashpay/dash/blob/bcd14b05cec7d94986f114ca17bbdadbee701d9b/src/test/net_tests.cpp#L140)) and therefore, would fail validation ([source](https://github.com/dashpay/dash/blob/bcd14b05cec7d94986f114ca17bbdadbee701d9b/src/evo/deterministicmns.cpp#L1219)). This has been resolved by changing the index to start from 1.

  * To avoid a potential "no user-provided default constructor" compile-time error, we now explicitly request the default constructor

   </details>

  * The reason why we track individual entries _within_ `MnNetInfo` in the unique properties map instead of `MnNetInfo` is that while `MnNetInfo`-like objects (because `MnNetInfo` itself only stores one value) could check _internally_ for duplicates, the uniqueness requirement for addresses is _across_ ProTx'es and therefore, we are concerned not so much as _how_ the addresses are bundled (`MnNetInfo`) but if the individual addresses (`CService`) are unique _across_ all known addresses.

  * We cannot use `const auto&` when iterating through `GetEntries()` as it uses `std::reference_wrapper<const T>` and `auto` will take on the type of `const std::reference_wrapper<const T>&` instead of the underlying `const T&` as intended, to trigger the conversion to the underlying reference, we have to explicitly specify the type, hence the usage of `const T&`.

  ## Breaking Changes

  None expected.
