NOTE:
The snapshots above have the values I used for testing in our lab.
Offset:
Refers to the octet that will be increasing its value.
Count:
Refers to the number of times the octet will be increased before getting back to the original value. In this case 0A.
Mask:
Refers to how numbers in the octet are going to be modified. If you use F the octet will increase from 0 to 9.
Value:
Refers to the octet’s staring value.
