Sorry I saw this mail only now. This is a rule. Actually it is an accident. We are losing one extra IP for every subnet. This is due to historical reasons. I wonder it is due to the conflict between having all 0s or all 1s for the host part of the IP address. I guess this was to make things easier for hardware level xor operations or something. 1 EXOR 1 = 0 0 EXOR 0 = 0 1 EXOR 0 = 1 0 EXOR 1 = 1 So if you have an EXOR gate in your router/switch, then all 1s and all 0s both lend to fast processing. Anyway one should read the history to figure out exactly what happened. -Girish _______________________________________________ To unsubscribe, email [EMAIL PROTECTED] with "unsubscribe <password> <address>" in the subject or body of the message. http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
