Zero octets can be shortened as long as it doesn’t change the meaning. For example, in the case of 127.0.0.1, the first octet (127) is always mandatory, and the zero octets can be shortened as follows:
127.1 — this is a valid shorthand for 127.0.0.1.
So, the command ping 127.1 is essentially equivalent to ping 127.0.0.1
