Well, you got IP Precedence correct. That is indeed 10100000. DSCP
46 however would look like this 10111000. Now, why is this important?
Now all you have to do is take those numbers and convert them to
either decimal or hexadecimal.
Let's look at the answers now:
You want to mark your ping with IP Precedence of 5.
IPP 5 = 1010 0000
= 0xA0
= 160 decimal
DSCP 46 = 10111000
= 0xB8
= 184 decimal
so when you do your extended ping you can enter it either as a decimal
number or as a hex number by preceding it with 0x
Make sense?
