0.0.0.0 is localhost, which is a great way to allow other software running on your computer to take the data and send it elsewhere. It's not a great IP address

0.0.0.0 is localhost, which is a great way to allow other software running on your computer to take the data and send it elsewhere. It's not a great IP address to use for "invalid".
Yes, 0.0.0.0 really resolves to 127.0.0.1 on Linux at least. Try it.
- oefrha 6y agoNot saying 0.0.0.0 should be used in this case, but if you have data sniffing software listening on port 80 or 443 without your knowledge (or really any port at all, but especially a privileged port), you probably have much bigger things to worry about than some ad hoc PoC sending data there.
