:: I don't think any RFC actually calls for this, but 1122 is probably
:: the relevant reference. From 3.2.1.3:
:: (g)  { 127, <any> }
:: 
::      Internal host loopback address.  Addresses of this form
::      MUST NOT appear outside a host.

RFC 990 seems to cover it though:

         The class A network number 127 is assigned the "loopback"
         function, that is, a datagram sent by a higher level protocol
         to a network 127 address should loop back inside the host.  No
         datagram "sent" to a network 127 address should ever appear on
         any network anywhere.
