DNS Domains

As described in RFC 2606 ↗ and RFC 6761 ↗, a number of domains such as example.com and example.org are maintained for documentation purposes. Sometimes you also need to differentiate between a customer domain and your own application domain, so Cloudflare has also registered some domains for you to use.

Examples:

• example.com
• example.org
• myappexample.com
• mycustomerexample.com

IANA also maintains more example domains documented here ↗.

IPv4 ranges

According to the Internet Engineering Task Force (IETF), there are specific IPv4 ranges used for documentation ↗:

Examples:

• 192.0.2.0/24.
• 198.51.100.0/24.
• 203.0.113.0/24.

These IP addresses are reserved and will not take anyone to live origins.
