The docs for Net::Ping say that it supports various different ways of checking a host is alive, and by default uses 'TCP', which attempts to connect to the TCP 'echo' port of the IP address you specify.

This is unlikely to work in a modern network environment (and is a different test to the ICMP ping your command line tool uses).

Try specifying the 'icmp' protocol and see if that helps. The docs say that this is the first arg to the ctor, so perhaps: 

my $p = Net::Ping->new('icmp');

The ctor also takes other arguments (including a timeout), which may be of interest to you.
