Why do we need to use [IP::addr [IP::client_addr]]?

Why can't we simply compare [IP::client_addr] on its own? I'm a bit confused as to why IP::addr has to be used...the thread below is what peaked my curiosity: http://devcentral.f5.com/Community/Group...

I was looking for a post from unRuleY which had more detail, but couldn't find it. I believe IP::addr does a more efficient byte comparison than you could do with a string comparison. And as Michael points out, IP::addr allows you to do CIDR comparisons that you couldn't easily do with string operations.
