I'm not sure which part you think is false?

Some larger companies use public IP addresses for everyone's desktop, but they're still behind a firewall. So these are "local" in the sense of behind their firewall, despite being "publicly" routable addresses.

An attacker can create a domain name pointing to any IP, including 127.0.0.1 and 192.168.1.1. So browsers won't gain any security by looking at the domain name.
