:: 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.
