Example Two - Mapping to an IP Address Range

192.168.0.2 to 192.168.0.4
Translated Destination = 10.50.165.1 - 10.50.165.3 (Range)

Packet Src IP = 192.168.0.2
192.168.0.2 = C0A80002 = 3232235522 = 11000000101010000000000000000010
(IP -> Hex -> Dec -> Binary)

Sticky IP Formula = Packet Src IP = 3232235522 [modulo] TransDest Size = 3
= 3232235522 [modulo] 4
= 1077411840.6666667 - 1077411840
= 0.6666667 * 3
= 2

Sticky IP Formula yields offset of 2.
