Restricting a page based on IP range

This is an really old question, but since it was not answered.

In Lucee you can just use isIPinRange() https://docs.lucee.org/reference/functions/isipinrange.html

https://docs.lucee.org/reference/functions/isipinrange.html

I don't know if this is available in the Adobe version of Coldfusion yet.

Hi Scotch123,

I think this UDF might help you to acheive that.

http://cflib.org/udf/isIPInRange

convert start & end of IP range to decimal, then simply check if the IP is

within that range (this is how the db based geolocators work).

function ipNumber(ipAddress) {

var a=listFirst(arguments.ipAddress,".");

var b=listGetAt(arguments.ipAddress,2,".");

var c=listGetAt(arguments.ipAddress,3,".");

var d=listLast(arguments.ipAddress,".");

return (a * 16777216) + (b * 65536) + (c * 256) + d;

}

</cfscript

Thanks a lot, guys! Much appreciated. I believe I was able to do it via IIS by excluding all IP except for our local range, but the CF snippets will come in very handy, too.

Cheers!

<cfset ipaddress = cgi.remote_addr>

<cfset classa = listgetat(ipaddress,1,".")>

<cfset classb = listgetat(ipaddress,2,".")>

<cfset classc = listgetat(ipaddress,3,".")>

<cfset classd = listgetat(ipaddress,4,".")>

<cfif classa eq 123 and classb eq 45 and classc eq 67 and classd lte 99 and classd gte 80>

     <!--- whatever you want to do --->

</cfif>

if (left(cgi.remote_addr, 9) is "123.45.67"

and right(cgi.remote_addr, 2) gte 80

and right(cgi.remote_addr, 2) lte 99)
