dpc, one question about searching for a node or id on Iroh/rostra:

So my id here is rsut5j319xfrsr8ud3rgua8nmxm6kegcjjggijc6te5ein4tyjw8my

I understand its some ed25xx public key, which is some 64 bit number.

Using just this id, anyone can find this ‘user’ on the Iroh network, if I understand this correctly.

Then, my question is, lets say I only had the first 32 bits of this id, would I be able to find this user or endpoint on the Iroh/rostra network?
