How to anti ARP spoofing

An open source solution for anti ARP spoofing is ArpON "Arp handler inspectiON". It is a portable ARP handler which detects and blocks all Man In The Middle attacks through ARP poisoning and spoofing attacks with a static ARP inspection (SARPI) and dynamic ARP inspection (DARPI) approach on switched or hubbed LANs with or without DHCP. This requires an agent on every host that is to be protected.

Another method to anti ARP spoofing

Another method to anti ARP spoofing, DHCP snooping, can be used on larger networks, but is limited to DHCP clients, and as such, can be easily circumvented.[clarification needed] The DHCP service on the network device keeps a record of the MAC addresses that are connected to each port, so it can possibly detect if a spoofed ARP has been received. This method is implemented on networking equipment by vendors such as Cisco, ProCurve, Extreme Networks, Dlink and Allied Telesis.

A simple anti ARP spoofing method

A simple anti ARP spoofing method that only works for simple ARP spoofing attacks is the use of static IP-MAC mappings. However, this only prevents simple attacks and does not scale on a large network, since the mapping has to be set for each pair of machines resulting in (n*n) ARP caches that have to be configured.
