It's the standard, is what it is:

$ telnet 1.2.3
Trying 1.2.0.3...
^C
$ telnet 1.2
Trying 1.0.0.2...

Though admittedly an old and not very useful standard... See the section
INTERNET ADDRESSES on e.g.
http://www.freebsd.org/cgi/man.cgi?query=inet_aton for a description of
the logic, such as it is (feel free to ignore the part about the VAX:-).
The above commands are from a Linux box, i.e. it's not (Free)BSD-
specific, but of course the logic is not described in Linux man pages.
