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, took notice of this one time i was exploring a transaction on the bitcoin explorer, but didn't take note of which explorer in particular.
I haven't ever heard of a blockchain explorer doing that and I doubt there is any. If there's a blockchain explorer doing such a thing, it can't do that for all addresses.
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.
