There are several IP address ranges reserved specifically for documentation and examples such as 192.0.2.0/24 and 2001:db8::/32. That's what they should have used.

It's cooler to use 172.16.0.0/12 because everyone just sees "192" and thinks it's part of 192.168.0.0/16.

That's a for LAN use. The other IPv4 example ranges are 198.51.100.0/24, 203.0.113.0/24 and 233.252.0.0/24.
