Earlier today, on my Ubuntu 14.04 I was running
nmap 192.168.0.1/24
And my machine had a legitimate hostname in the form of [hostname].[wifinetwork]. However, when I run the same command now, my machine's hostname is bogon, which appears to be short for a bogus IP address. I've tried a bunch of keywords around the term bogon but I don't understand what caused this change or how to fix it.
What other commands should I run to better understand this problem?
