I found this great tool on ZJ's blog and another source. I used the 4.1 trial version last semester when our class network was unstable, and it worked pretty well—powerful features and all. After the ARP virus issue settled down, I stopped using it, mainly relying on my boss's v2.x for ARP protection when needed, so I didn't pay much attention to updates. Now that there's a fully unlocked v4.2 version available, who would still use the older versions? That said, I've heard that 360 also released an anti-ARP spoofing tool. Not sure how good it is, but I'll try it sometime if I get the chance.
Does your network frequently disconnect? Do you often experience IP conflicts?
Are you concerned about communication data being monitored (such as MSN, QQ, EMAIL)?
Is your network speed restricted by network management software (like Jusheng Network Manager or P2P Killer)?
Are you suffering from various ARP attack tools (such as Network Enforcer, Network Scissors, or LAN Terminator)?
