The Internationalized Deliberately Unreadable Network NOtation (I-DUNNO)


   Domain Names were designed for humans, IP addresses were not.  But
   more than 30 years after the introduction of the DNS, a minority of
   mankind persists in invading the realm of machine-to-machine
   communication by reading, writing, misspelling, memorizing,
   permuting, and confusing IP addresses.  This memo describes the
   Internationalized Deliberately Unreadable Network NOtation
   ("I-DUNNO"), a notation designed to replace current textual
   representations of IP addresses with something that is not only more
   concise but will also discourage this small, but obviously important,
   subset of human activity.

1.  Introduction

   In Section 2.3 of [RFC0791], the original designers of the Internet
   Protocol carefully defined names and addresses as separate
   quantities.  While they did not explicitly reserve names for human
   consumption and addresses for machine use, they did consider the
   matter indirectly in their philosophical communal statement: "A name
   indicates what we seek."  This clearly indicates that names rather
   than addresses should be of concern to humans.

   The specification of domain names in [RFC1034], and indeed the
   continuing enormous effort put into the Domain Name System,
   reinforces the view that humans should use names and leave worrying
   about addresses to the machines.  RFC 1034 mentions "users" several
   times, and even includes the word "humans", even though it is
   positioned slightly unfortunately, though perfectly understandably,
   in a context of "annoying" and "can wreak havoc" (see Section 5.2.3
   of [RFC1034]).  Nevertheless, this is another clear indication that
   domain names are made for human use, while IP addresses are for
   machine use.

   Given this, and a long error-strewn history of human attempts to
   utilize addresses directly, it is obviously desirable that humans
   should not meddle with IP addresses.  For that reason, it appears
   quite logical that a human-readable (textual) representation of IP
   addresses was just very vaguely specified in Section 2.1 of
   [RFC1123].  Subsequently, a directed effort to further discourage
   human use by making IP addresses more confusing was introduced in
   [RFC1883] (which was obsoleted by [RFC8200]), and additional options
   for human puzzlement were offered in Section 2.2 of [RFC4291].  These
   noble early attempts to hamper efforts by humans to read, understand,
   or even spell IP addressing schemes were unfortunately severely
   compromised in [RFC5952].

   In order to prevent further damage from human meddling with IP
   addresses, there is a clear urgent need for an address notation that
   replaces these "Legacy Notations", and efficiently discourages humans
   from reading, modifying, or otherwise manipulating IP addresses.
