It seems that this case has the name Dotless IP Address Security Issue
and KB article #168617 http://support.microsoft.com/?kbid=168617
describes it even in IE4.
Correct if I'm wrong.

IIRC, Microsoft changed that as one of the security updates to IE. For a
time, it was a popular phishing trick. I also remember there was a way
to do that (or something similar) to bypass the security zones in IE and
make it think it was a trusted site, but can't find that reference at hand.
The "rest" of windows will still do it though. Try "ping 2887060730" or
"telnet 2887060730 80".
