Net::Libdnet provides a simplified, portable interface to several low-level networking routines, including network address manipulation, kernel arp cache and route table lookup and manipulation, network firewalling, network interface lookup and manipulation, network traffic interception via tunnel interfaces, and raw IP packet and Ethernet frame transmission. It is intended to complement the functionality provided by libpcap. All the original and obsolete functions return undef and print a warning message to the standard error when a problem occurs. The obsolete functions are: addr_cmp, addr_bcast, addr_net, arp_add, arp_delete, arp_get, intf_get, intf_get_src, intf_get_dst, route_add, route_delete, route_get. These obsolete functions will continue to work, to keep backward compatibility, but should not be used anymore. The new APIs should be preferred. There are two new APIs, one is the low-level one, matching libdnet functions, and the other one is a high-level API, matching a more Perl object oriented programming. This latest one is highly preferred. Net::Libdnet module implements the low-level API. The high-level API is accessible by using the following modules: Net::Libdnet::Intf, Net::Libdnet::Route, Net::Libdnet::Fw, Net::Libdnet::Arp, Net::Libdnet::Eth, Net::Libdnet::Ip and Net::Libdnet::Tun.
