From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Why do people hide local ip address on fastfetch.
Overly cautious and slightly tech illiterate. I’m working on the latter though!
For reference, sharing your local IP address is a little like saying “I’m in room 223” (local IP address) and not saying what building (network) you’re in. Someone can’t walk into 223 in a different building and get to the same room you’re in.
Honestly, even if someone knew what network you were on, a local IP address wouldn’t be that useful because even if they successfully got on your network, as long as you have a properly-configured firewall and no vulnerable network-exposed services on your system, they can’t really do anything.
Honestly, while it’s still not a bright idea to tempt fate like that, even sharing your public IP isn’t that bad for the same reasons if it’s a competent home user; the worst that can happen on a properly-configured network is that someone tries and fails to exploit vulnerabilities that aren’t there and MAYBE drum up your internet bill. Also, for most ISPs, your public IP changes pretty often anyway, usually something like every few days to a week, due to changing DHCP leases.
Thank you for all that info! I appreciate it. Definitely furthers my goal of tech literacy. I’ve always been competent at using computers but don’t know much about anything more in depth.
