And I also think there's also a bitcoin blockchain explorer that has that feature which can show the user other types of bitcoin address that is associated or shares the same private keys with the address they are at its transaction log at that time,
-snip-There is no way to know what addresses have been derived from the same private key unless you have the private key or there's a transaction made from one of those addresses.
The PubKeyHash that you can derive from the address can be encoded into different type of addresses without the associated public/private key.
