Please provide the following information
qBittorrent version and Operating System

If on linux, libtorrent and Qt version
What is the problem
The hostname of another peer points to my hostname.

It's not qbittorrent's fault.
PTR record(Pointer record), the PTR value can be anything or domain name.
For example
First, my ip is 1.2.3.4 and set the PTR record to 1.2.3.4.is.mine
After reverse DNS 1.2.3.4, and i got resolved hostname: 1.2.3.4.is.mine...
Now, expect my hostname is c0re100
Set the PTR record to localhost
After reverse DNS1.2.3.4 and i got resolved hostname: localhost...
In OS level, localhost=your hostname, so i got resolved hostname c0re100 actually...
Sorry, maybe I didn't describe it clearly...
c0re100
