8Format
9    Ambit uses a cool format for specifying targets. Here's some examples.
10
11    
12
13    Check one host for one port.
14
15    ambit 192.168.1.1:22                       
16
17        
18
19    Check two host for two ports, using commas.
20
21    ambit 192.168.1.1,192.168.1.2:22,80
22
23     
24    
25    Check a range of hosts for a range of ports.
26
27    ambit 192.168.1.1-192.168.1.100:100-300
28
29    
30
31    You can combine any of these formats.
32
33    ambit 192.168.1.1,192.168.1.5-192.168.1.200:20-23,80,8000,8080,500-1000
34
35
36
37    You can also have multiple groups.
