    ping localhost..

    hi guys....
    yesterday wen i was jus pinging localhost..
    instead of writing 127.0.0.1 i wrote 127.9.0.3
    soo C:\>ping 127.9.0.3

    Pinging 127.9.0.3 with 32 bytes of data:

    Reply from 127.9.0.3: bytes=32 time<10ms TTL=128
    Reply from 127.9.0.3: bytes=32 time<10ms TTL=128
    Reply from 127.9.0.3: bytes=32 time<10ms TTL=128
    Reply from 127.9.0.3: bytes=32 time<10ms TTL=128

    n after that wen i ping to any address in the format 127.x.y.z
    it replyed from same address..
    while i am on windows nt in my lab..
    n wen i tried in my home on my comp having windows xp
    reply came from 127.0.0.1

    so although i know the special class of ip addresses starting from 127. as the first octet
    i wanna know why is their difference between NT n Xp..
    n why its really happening
    i mean do system uses it for system file access or wat..

    address in the range 127.x.x.x are loopback addresses...
    check out RFC 1166

    Lightbulb hint

    127.9.0.3 <-- could be your local IP address in the lab.

    127.0.0.1 <-- your local IP address at home.

    AFAIK, pinging local IP addresses could have a "reply from [your local adress]..." reply.

    You could read more info about TCP/IP Tools & Utilities here - ftp://ftp.rfc-editor.org/in-notes/fyi/fyi30.txt

    and ping definition here - http://www.google.com/search?q=defin...en-US:official

    Why did you type in the 'wrong' IP ?
    What were you thinking of at that time ?

    I'm in agreement on loopback, just curious as to why you typed it out wrong in the first place. Could it be something you were working on ?
