> In some use cases, there will be many hosts from which the user can
> impersonate.
> This requires specifying many ips in the XML configuration.
> It is cumbersome to specify and maintain long list of ips in proxyuser.hosts
> The problem can be solved if we enable proxyuser.hosts to accept ip ranges in
> CIDR format.
> In addition, the current ip authorization involve a liner scan of the ips and
> an attempt to do InetAddress.getByName() for each ip/host.
> It may be beneficial to group this functionality of ip authorization by
> looking up "ip addresses/host names/ip-ranges" into a separate class. This
> could be reused in other usecases which require similar functionality
