Lookup targets with CIDR
What version of fleet are you using (fleet version --full)?
fleet - version 2.0.1 branch: master revision: d01727dff26683ba29424fbdb7e58e403ab6210d build date: 2018-11-26T19:21:48Z build user: zwass go version: go1.11.2
What operating system are you using?
CentOS Linux release 7.5.1804 (Core)
What did you expect to see?
When I select targets I expect to search them with IP address or CIDR, but I can lookup only with hostnames which is pretty uncomfortable. Also, IP address lookup is suggested on input placeholder.
IP Address input is possible:

As for CIDR, this is a great idea, but initially looks nontrivial to implement so I won't give any promises on its implementation.
In my case, this function does not work - I can search only with hostnames. Is this feature already implemented in version 2.0.1?
This feature has existed for at least a year. When you click "select targets" do you see any hosts? If you start typing the IP for one of those hosts, you get no results? Can you please make a screencap and add it here?
