When using the isInNet() function, anything passed that isn't an IP
address needs to be looked up in DNS to resolve it's IP address. If your
clients are not able to resolve external addresses from their configured
DNS servers then you will not be able to use this function (unless you
want to wait until things timeout) :-(
