Above are the entries obtained from my windows vista's arp table.

As most of us normally know, the arp table normally displays ip address within the LAN range in conjunction with the MAC address. But, there's something weird about my arp table above. Note the ip address i bolded. As an effort to get rid of the above bolded ip, i try using the arp -d command. Although successful, the bolded ip are being cache to the arp tables again when i connect to the LAN.

It is weird to have such ip outside my LAN range. Due to my curiosity, i did a whois lookup on the bolded ip. These are the outputs:

Well, it looks legit at first as it originates from IANA.

Hmm....i was wondering why IANA's ip is listed in my arp table. Can someone enlighten me about this? Is my LAN being intrude by outsiders?

Any help will be appreciated.
