Cita: Although 127.0.0.1 is the most commonly utilized address for localhost, any IP address in the 127.*.*.* range should also function in the same manner.
Si haces un ping a 127.233.45.67 te responderá el localhost o 127.0.0.1,
Por lo que parece que 127.0.0.0/8 corresponde a 127.0.0.1
http://tools.ietf.org/html/rfc3330 Cita: 127.0.0.0/8 - This block is assigned for use as the Internet host
loopback address. A datagram sent by a higher level protocol to an
address anywhere within this block should loop back inside the host.
This is ordinarily implemented using only 127.0.0.1/32 for loopback,
but no addresses within this block should ever appear on any network
anywhere [RFC1700, page 5].
