About this block
192.0.2.0/24, 198.51.100.0/24 and 203.0.113.0/24 (TEST-NET-1, -2 and -3), and 2001:db8::/32 in IPv6, are reserved for examples in books, manuals and RFCs, so an example never points at someone's real server.
Where you'll see it
- Documentation and tutorials.
- Sample configuration files, where they should be replaced with real addresses.
