Well, to answer my own question, no they can't. Anything greater than 127.255.255.255 exceeds the size of CF's integer type and the bitwise operators throw errors. This begs the question... How does CF represent numbers larger than 32 bit signed integers? Does it internally use longs (at least on 32 bit systems) or does it revert to using strings? If it uses strings, that's got to be one hell of a performance hit when numbers get that large.
