Burp Intruder doesn't accept IP address ending in 0

Hello! Today to my chagrine I discovered that Burp Intruder refuses to launch an attack against a host ending in .0, complaining "Invalid target". While this would be the case if it was your run-of-the-mill /24, I'm on a /23, and this is a valid host. Repeater and Burp Proxy work totally fine with it.
