Does that actually work? If ISPs assign, say, 8.8.8.0/24, then you're going to have trouble determining whether that DNS lookup bound for 8.8.8.8 is 8.8.8.8 on

Does that actually work? If ISPs assign, say, 8.8.8.0/24, then you're going to have trouble determining whether that DNS lookup bound for 8.8.8.8 is 8.8.8.8 on the Internet or 8.8.8.8 on some link-local host.
Because people typically use IPs designated as private behind a NAT, this isn't a problem in practice. But if you start using publicly-routable IP addresses internally, then you can create some fun problems. Actually, not even that fun. Just annoying.
- m3kw9 6y agoNAT usually translates a private ip to global ip, in your case there should be an internal DNS to resolve internal names
- p1mrx 6y agoYou're missing the point; 8.8.8.8 was just an example. For any public IP assigned inside your network, clients trying to reach to the real address won't be able to get there, because they'll hit the internal one instead.
