how to exclude specific hostname from recording

In some situation, visits come from different IP address, but use the same hostname. These visits usually access one page each time. Even more,they some time access the same web page every ten or twenty minutes.

I use wassup plugin to count valid accesses to my website. The visits described above definitely cannot be thought as valid accesses and should be excluded. Because they use different IP addresses but with the same hostname, it is impossible to put all IP addresses in Recording Exceptions. So adding hostname in Wassup exception options is the one way to solve this problem, I think.

Can the plugin authors add this option?

Thank you.
