I think this had been answered already ! Smilie ( Not sure, though )

Code:
ping <hostname> 2>/dev/null 1>&2

Now you have the required value in $?

It complains about the output redirect, which is strange cause it is correct as defined. However you can try changing the redirect.

Instead of:
ping sun8 2>/dev/null 1>&2
try:
ping sun8 >/dev/null 2>&1

if that doesn't work you can try:
ping sun8 > /dev/null 2>/dev/null
