Don't forget that xymon does more than just ping test (which is all
'noconn' modifies). There are a lot of scenarios where ICMP traffic is
blocked but you'll still be able to hit --thus, test-- port 80 or some
other service.

For those hosts, xymon still needs to be able to look up the IP address if
all it has is a name, so if you want to prevent lookup attempts on the
fake name you're going to need both tags.

Think of "testip" as "doesnotresolve"
