I happen to know ;-).

When you have more than two sequences of digits separated by dot,
like IP address 192.168.1.1, you are telling Perl to interpret the
sequence as a string, each byte of it is the number denoted by these
digits.  I believe this was invented primarily for IP addresses, but
it does not have to be just four digits.  To wit:

    $ perl -e 'print 65.66.67;'
    ABC
    $ perl -e 'print 65.66.67.68.69;'
    ABCDE

Of course, 65.66 is not AB, but a floating-point number that is
between integers 65 and 66:

    $ perl -e 'print 65.66;'
    65.66

True.
