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

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..
