Reminder that the only safe dummy domains to use are:

- example.com
- example.net
- example.org

And nowadays there's also a safe dummy TLD: .example

These are safe because they are reserved by IANA as as special-use domain names for documentation purposes on direction of IETF in RFC 2606 and RFC 6761.

Any other domain can be registered and as such should _never_ be used as a dummy domain for documentation or as eg. an example in default configs.

@voxpelli I wrote a doc on this. Not only for domains, but also IP addresses and phone numbers.

@atoponce @voxpelli "While the area codes 600, 622, 633, and 644 are identified as "non-geographic", they are assigned to Canada." 🤯

@raboof @voxpelli Looks like I can add area codes 677 and 688 also as Canadian non-geographic area codes.
