One of my main desktops on my home network is Mandriva 2010.2 x86_64.  I 
have coded it with a static IP address of 192.168.1.107.

This morning, I was running Wireshark, and I noticed this exchange at 
least twice every minute, ad infinitum.

23489	4030.195572	Cisco-Li_ea:bf:6a	Micro-St_ab:cd:ef	ARP	Who has 
192.168.1.107?  Tell 192.168.1.1	60

23490	4030.195589	Micro-St_ab:cd:ef	Cisco-Li_ea:bf:6a	ARP	192.168.1.107 
is at 6c:62:6d:ab:cd:ef	42

Why doesn't the router remember this?  I would have thought he would 
have got it once on startup, and then retained the information until 
shutdown.

Thanks,
JimR
