Had a previous employee or I discovered it on the network segment after we had some weird routing issues and had to get that cleaned up. I don't know why anyone would do that when there is tons of private IP space.
Excuse 1: "We'll never connect to the internet!" Excuse 2: "It's only temporary!" Excuse 3: Typo (At some customers customer I found 192.!168 address which where apparently a typo but in use for years so nobody wanted to change it.) I also know one company who is using (has used?) 2001:8db::/48. I suggested to get v6 PI an properly implement IPv6 but never heard from them again. Excuse 4: "We used the addresses from out training material." - I heard this story some time ago: A large German government agency wanted to implement IP(v4) and the people attended a course about this new TCP/IP stuff at $Vendor. The training material was prepared by a student who was using his university's /16 as an example. BTW: Is the Cisco WLC 1.1.1.1 as default address for DHCP?
