127.0/8 are internal to the local host. So, yes it's valid but it
doesn't get around much. :-)
See RFC 3330 and RFC 1700.
From RFC3330:
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].
