Hi Experts,
Am new to the networking.Is there any specific reason why
only 127.0.0.1 is used as a loop back address,why not other addresses.
Historical convention? The standards say that 127/24 is reserved for
loopback addresses. You could use any other 127 address, I suppose (and
I've done so), but I suspect 127.0.0.1 is so firmly entrenched in the
minds of admins and developers that you'd probably find things that
break if you tried a different address.
Using a non-127 address would have ill effects, if it even worked. The
reason is that the IP stack itself understands that loopback addresses
are special, and they are given special treatment in the stack.
