I thought this is basic knowledge of everyone technically engaged in Internet stuff. But apparently, this isn't the case, despite its well-known and very readable documentation! [1] It says: 1) There are exactly 3 domains the IANA keeps free for that purpose: example.com example.net example.org 2) In addition, all domains under the following 3 top level domains can be used freely for that purpose: *.test *.example *.…

Along a similar line, there are two reserved IP prefixes for use in documentation and examples;

IPv4: 192.0.2.0/24 - as described in RFC3330, http://www.faqs.org/rfcs/rfc3330.html

IPv6: 2001:db8::/32 - as described in RFC3849, http://www.faqs.org/rfcs/rfc3849.html

A related topic that drives me nuts after years of operations is the fairly widespread use of '.int' to represent private DNS on an internal network. '.int' is a rarely used TLD for international organizations created by treaty. It is so rare that many browsers do not recognize it as such and will ship you off to a search for 'www.nato.int', for example. Nonetheless, it drives me batty whenever I see 'dns1.int'.

That is so true... Most developers who get an account with Mailgun ( http://mailgun.net ) get so excited about the live email log or for some other reason... they love to fire up emails to @test.com. We have thousands of emails in our queue destined for test.com at any given moment. Guys, please stop: what makes you think test.com can't be a real destination? :-) Actually, they don't have a mail server for that domai…

Ironically, I just came across some potentially real email addresses in the Mailgun docs and sample code, i.e.: http://cl.ly/1L1C0O2A081x000t382z You might want to edit those.

We own profista.com and use it for testing ourselves. Using it in the docs helps us see how many people are trying out the samples.

I wish all our users would read the docs as carefully as you do! :)

Worse yet, some internal networks use .local, despite its standard use for mDNS.

*.local is a great example of why not to use a domain that just 'sounds good' as an internal dns suffix, as it is used by bonjour/avahi[1]

I had to rename an entire corporate network once because the previous folks thought .local "looked good". It cause constant issues with clients that had bonjour or avahi running.

I've never been a fan of foo and bar as example names. Particularly in code examples, I can never keep them straight because the names are meaningless. Anyway, we already have example.com for this purpose.

Perhaps reading RFC 3092 - Etymology of "Foo"[1] might be helpful.

Personally, I was familiar with the acronym FUBAR first, so it comes as natural to me as most mainstream, American acronyms.

Here's my hand up admitting I made that mistake back in the day. At least it was only our staging server cluster, and not an entire network...

Ironically, example.com/net/org were themselves taken over by IANA because they were the recipient of so much test email.

ETA: I am now starting to doubt my memory here, and Google's USENET archive search is broken. Sigh.
