Example domains

Did you know that there are official example domains that can be used in documentation? example.com, example.net and example.org are all example domains of the IANA, the Internet Assigned Numbers Authority, which are explicitly intended for use in documentation.1 In documentations or even in sample code I often stumbled over examples where no official sample domain was used, but one that can actually be registered. It is not recommended to use such a domain, because you can’t make sure that it will be registered once and maybe unintentionally data will end up with strangers.

See RFC 2606 and 6761 as well as this official IANA site. ↩︎
