172.16.5o.41

It looks like you’re referencing the string 172.16.5o.41 .

At first glance, this resembles an IPv4 address, but the 5o part is unusual because IPv4 addresses use only decimal octets (0–255) separated by dots — no letters. The o might be a typo for 0 , making it 172.16.50.41 , which is a valid private IP address in the 172.16.0.0/12 range. 172.16.5o.41
