Hello,

I'm trying to understand arp a little better. Let say that I do an IP config and I gathered the following information:

IP Address. . . . . . . . . : 10.0.0.98
Subnet Mask . . . . . . . : 255.255.0.0
Default Gateway . . . . : 10.0.255.254

I do an arp -a command and received

Interface: 10.0.0.98 on Interface 2
Internet Address Physical Address Type
10.0.255.254 00-e0-b0-ac-ac-a8 dynamic

I then ping ping 10.0.255.255 and then do another arp -a command and come up with

Interface: 10.0.0.98 on Interface 2
Internet Address Physical Address Type
10.0.116.21 00-00-f4-a9-9d-d4 dynamic
10.0.224.34 00-00-1d-0f-4b-71 dynamic
10.0.108.2 00-00-f4-a9-98-21 dynamic
10.0.17.129 00-00-f4-b1-b6-57 dynamic
10.0.7.141 00-10-5a-05-ef-f9 dynamic
10.0.0.153 00-60-b0-79-c3-80 dynamic
10.0.3.3 00-e0-34-8b-2f-ff dynamic
10.0.1.250 00-00-0c-4e-32-90 dynamic
10.0.1.251 00-00-0c-4e-32-90 dynamic
10.0.255.252 00-e0-b0-ac-ac-a8 dynamic
169.254.0.1 00-00-09-6c-4b-58 dynamic

Where did all of these new entries come from?
