Field Description Default
Mask In this field, specify (in Hexadecimal) the value that your Prestige should
logically qualify [and] the data in the packet. Since Length is given in bytes,
you need to enter in twice the length hexadecimal numbers for this field. For
example, if Length were 4, then a valid Mask must have 8 hexadecimal
numbers, like 1155ABF8.
Value In this field, specify (in Hexadecimal) the value that your Prestige should use
to compare with the masked packet. The value should align with Offset.
Since Length is given in bytes, you need to enter in twice the length
hexadecimal numbers for this field. For example, if Length were 4, then a
valid Value must have 8 hexadecimal numbers, like 1155ABF8. If the result
from the masked packet matches Value, then the packet is considered
matched.
