Converting IP Addresses To Integer Values With ColdFusion

gistfile1.txt

<!--- Set the IP address. --->
<cfset ipAddress = "10.150.160.228" />

<!--- Break the IP address into numeric units. --->
<cfset ipParts = listToArray( ipAddress, "." ) />

<!--- Create a running total for our numeric IP equivalent. --->
<cfset ipNumber = 0 />

<!---
	Loop over the parts of the array. For each part, we are going
	to let the 8 bits be continually shifted over to add exclusive
	bits to the running total.
--->
<cfloop
	index="offset"
	from="1"
	to="#arrayLen( ipParts )#"
	step="1">

	<!---
		Since each IP unit is a max of 255, we need to shift it
		over (bit-wise) for multiples of 8.
	--->
	<cfset ipNumber += bitSHLN(
		ipParts[ offset ],
		((arrayLen( ipParts ) - offset) * 8)
		) />

</cfloop>

<!--- Output the resultant IP number equivalent. --->
<cfoutput>
IP Address: #ipAddress#<br />
IP Number: #ipNumber#

</cfoutput>
