192.168.03? wtf? I have no idea why this works, but I can reach ANY machine without the last dot inside the network.
Any ideas?

do some research into how the ip stack works.

From glibc's function inet_aton() (used to convert dotted-quad IP addresses to their binary equivalent):
| Code: | /*
* Internet format:
* a.b.c.d
* a.b.c (with c treated as 16 bits)
* a.b (with b treated as 24 bits)
*/ |
There is another format that is not in the comment: a single number (interpreted as a 32-bit "binary" IP address, sometimes called a "long IP address").
For example, all those point to Google (64.233.183.99):

Tank you, but one STUPID little question. Can you give me the math for the conversation? For each one of the examples?
