VS: VS: DNS Misconfiguration on- http://cyberia.net.sa/

[Jukka Pakkanen]

Yes but I think the rfc1537 refers, and the recommendation always was "localhost." hostname, which refers to name "localhost", not "localhost.domain". Then I guess, this was already wrong in the O'Reilly "DNS and BIND" book (have to check that), which I remember using as a guideline to set up our first domains/zones.  And from that, the setting was copied later on to all new domains too.

Yes, it used to be recommended -
https://tools.ietf.org/html/rfc1537#section-10

But not any more, because -
https://seclists.org/bugtraq/2008/Jan/270

I also only found out about this recently(ish) - https://www.dns.cam.ac.uk/news/2017-09-01-localhost.html
