Why does pinging 192.168.072 (only 2 dots) return a response from 192.168.0.58?

ip-address

I mistakenly missed the dot off of an IP address and typed in 192.168.072.
To my surprise I connected to a machine at 192.168.0.58

If I ping 192.168.072 I get responses from 192.168.0.58.

Why is this?

I'm on a Windows PC on a Windows domain.

If I ping 192.168.72 I get a response from 192.168.0.72, so it seems the 0 in 072 (in my original mistake) is significant.
