    I have a windows xp pro, I am trying to ping a modem that I have. The modem is set up with the IP address of 10.10.1.65. I connect to the modem when I ping that ip address, but not when I ping 10.10.1.065. Can someone explain the difference to me?

    Those are two different addresses:D

    Each section of the address goes from 001 to 255.

    If ‘member my programming right.
    An IP address is a binary 32 bit number broken up into 4 bytes.
    For convince we write the decimal equivalent. The numbers for each byte can only be between 0~255.

    Why you can’t ping .065 when you can .65 is a mystery – the leading 0’s shouldn’t do anything. Are you sure you typed zero and not the letter O?

    .001
    .002
    .003
    skip a few
    .065
    skip several
    .65

    The addresses are like phone numbers...If moms phone number is 555-6565 and you dial 555-0656 you're going to get someone else...

    Illuminating to say the least.

    Imagine a simple non event like a leading zero **** up a computer.

    Considering computers only know 0's and 1's a leading zero can hardly be classed as a non event :D
