I am needing to perform a leasequery to multiple servers. HI have tried the following code but it keeps locking on the second server. I cannot find anything online as an example. Can someone provide some assistance?

!/usr/bin/perl -w

use IO::Socket::INET;
use Net::DHCP::Packet;
use Net::DHCP::Constants;

$mac=$ARGV[0];

@dhcp = ("10.16.30.4","10.16.30.5","172.31.45.248","172.31.45.249","17
+2.31.35.248","172.31.35.249");

foreach $server (@dhcp) {

  print "$server\n";

# create a socket
  $handle = IO::Socket::INET->new(Proto => 'udp',
                                  Broadcast => 1,
                                  PeerPort => '67',
                                  LocalPort => '67',
                                  PeerAddr => $server);

# create DHCP Packet
  $inform = Net::DHCP::Packet->new(
                      op => BOOTREQUEST(),
                      Htype  => '1',
                      Hlen   => '6',
                      Ciaddr => '0',
                      Chaddr => $mac,
                      Giaddr => $handle->sockhost(),
                      Xid => int(rand(0xFFFFFFFF)),     # random xid
                      DHO_DHCP_MESSAGE_TYPE() => DHCPLEASEQUERY
                      );

# send request
  $handle->send($inform->serialize()) or die "Error sending LeaseQuery
+: $!\n";

#receive response
  $handle->recv($newmsg, 1024) or die;
  $packet = Net::DHCP::Packet->new($newmsg);
  $data = $packet->toString();

  $handle->close();

}

print "$data\n";
