Enter one or more hosts separated by spaces, commas or semi-colons.
Hosts can be by DNS or IP address.
Host names can optionally be followed by a port number:
www.ibm.com:443
Host ranges can also be identified via classless inter-domain routing (CIDR):
10.10.8.8/30
Finally, host ranges and ports can be mixed, as in:
www.ibm.com:443/30, 10.10.8.8:80/28
