The private ranges
| 10.0.0.0/8 | Private (RFC 1918) |
| 172.16.0.0/12 | Private (RFC 1918) — 172.16.0.0 to 172.31.255.255 |
| 192.168.0.0/16 | Private (RFC 1918) — most home routers |
| fc00::/7 | IPv6 unique local, usually starting fd |
Private is not the same as special-use
Some addresses are neither private nor public: 127.0.0.1 is loopback, 169.254.x.x and fe80:: are link-local, and 100.64.0.0/10 is the shared space providers use for carrier-grade NAT. None of them are routed across the internet.
Why does my computer show a different address from this page?
Your computer usually has a private address on your own network, like 192.168.1.23. Your router swaps it for one public address on the way out, and that public address is what websites see. See yours.
