[ih] Dotted decimal notation

[Brian E Carpenter]

Can anyone recall when and by whom the dotted decimal notation for IPv4
addresses was invented? This text first appeared in RFC820 (January 1983):

   One commonly used notation for internet host addresses divides the
   32-bit address into four 8-bit fields and specifies the value of each
   field as a decimal number with the fields separated by periods.  This
   is called the "dotted decimal" notation.  For example, the internet
   address of ISIF in dotted decimal is 010.002.000.052, or 10.2.0.52.

The leading zeroes are not considered valid these days.
