Gregory's Server@sindarina 0.0.0.0 is a valid IP address to use for documentation and testing because it literally routes to nowhere.

 @sindarina Just checked Wikipedia, and you're right. I guess I've only ever seen 0.0.0.0 used to point something to nowhere. I had no idea it could be used as an actual IP address. I just thought it was the equivalent to /dev/null.  @RachaelAva1024 It's part of the special purpose addresses, see; https://www.iana.org/assignments/iana-ipv4-special-registry/iana-ipv4-special-registry.xhtml and basically never used directly, only behind the scenes, which is also why it's not particularly useful in testing, or documentation, because it just means βthis hostβ, which could have one address, or ten. For local testing on the host itself, there's the localhost address. |
@RachaelAva1024 No, it isn't. Just stick with the documented test ranges.
