It's netmask 255.255.248.0 shown, not 255.255.255.248.

It would make a good reason but the numbers given are correct. The
netmask is the same as a /21. 192.168.131.21 is on his 192.168.128.0/21
network[1]. I notice he misspelled kernel though, with no network he
had to type it in, it's still possible there is a mistake that he didn't
notice and typed what he thought he saw.
