Old habits. Just as a general rule, I black out most IPs, even when private. I used to deal with a lot of horribly insecure devices at work, with default passwords that couldn’t be changed, no port security (so anyone who found the wrong Ethernet port could connect to the network,) etc…

So anyone on the network could fuck things up if they were on the wrong wifi and tried to reconfigure something they shouldn’t be touching. It was only an issue a few times, since the vast majority of people using said network were other techs who knew what they were doing. But there were a few times that someone screenshotted something, it got passed around to all the managers, and someone who didn’t know what they were doing got curious and went digging when they saw the IPs.

It was never anything catastrophic since the network wasn’t even connected to the internet, and we had backups of any important settings. But it was just a practice that we all eventually picked up, to prevent random employees from sniffing around. Because it always sucked to come into work the next morning, and discover that a particular piece of gear wasn’t working properly because someone decided to tick a stray checkbox or change a polling rate.
