You're right. But is it really desirable? If, for some reason, you
need to ping an address generated by a program which outputs the address
in 4 triplets, you get a surprise.
Might it not be a better idea to stress that octal values and
hexadecimal values should be escaped, ie. \OOO (for octal) and \xXX (for
hex)?
Best regards,
Brian
