I don't know if it's ever been blessed by a formal standard, but
that way of interpreting an IPv4 address is widely implemented in
inet_aton() and friends.  The 4.2BSD inet(3) manual page documents
that interpretation, and on most (all?) systems I've ever used,
"ping 127.1" is a shortcut for pinging the loopback address.
