RFC 2606 - Domain names for testing

In this blog, often the output or the example used needed to be masked before posting. To protect the original server/identity. But when it comes to domain names, we can't simple quote some random name, it might be an active domain (in the future, if not now).


Also, for documentation or presentation, we tend to use mock up domain, server or host name. How to make sure that server, domain or host name is not in used?

In RFC 2606, there are domain names that serve this purpose :

The Internet Assigned Numbers Authority (IANA) also currently has the
following second level domain names reserved which can be used as
examples.

example.com
example.net
example.org

Now, we can quote example.[com|net|org] domain name in our examples, documentations & presentation without worrying the domain names might confuse the audience or clashing with existing domain names.

Au revoir !!!
