No, the restricted ranges are only
Class A:
10.0.0.0 to 10.255.255.255
Class b:
172.16.0.0 to 172.31.255.255
Class C:
192.168.0.0 to 192.168.255.255
Class D: for multicast
224.0.0.0 to 239.255.255.255
Class E: reserved for experimental use
224.0.0.0 - 239.255.255.255
And the APIPA ... Automatic private ip address:
169.254.0.0 to 169.254.255.255
And then there's obviously specific IP's like 0.0.0.0, 127.0.0.1,
255.255.255.255, and so forth.
Actually, note that 0.0.0.0 to 0.255.255.255 isn't allocated
And also note that 127.0.0.0 to 127.255.255.255 is reserved for loop back.
Not just 127.0.0.1.
Take care,
Sina

I was intrigued by the discussion of Tyler's IP address issue. I know about
the 10.X range, and the 192.168.X range, and I seem to recall that there are
other restricted ranges. Is one of them a 72.X range? I am having a bit of
an issue right now with a user whose ISP hands him a dynamic address
starting with 72, and wonder if it might be a restricted IP address.
