A set of helper subroutines to support parts of the Netdisco application.
|

There are no default exports, however the C<:all> tag will export all
|
|
subroutines.

=head2 is_discoverable( $ip )
|
|
|
|
Given an IP address, returns C<true> if Netdisco on this host is permitted to
|
|
discover its configuration by the local configuration.
|
|
|
|
The configuration items C<discover_no> and C<discover_only> are checked
|
|
against the given IP.
|
|
|
|
Returns false if the host is not permitted to discover the target device.
