#157 Unexpected ARP requests to IP X.X.X.127

[jennie]

If the device (with slpd) set IPv4 address to x.x.x.127, all devices(with slpd) in the same local network would send ARP request to the x.x.x.127 in the same time. If the ip is not x.x.x."127" (end with 127) or stop slpd the problem wont happen

Expected result : the arp request should occur while the device attempt to connect to each other.The address x.x.x.127 should not be a special case.

(The attachment is Wireshark log, you may use the filter: arp to see what's happened.

The occurrence rate is 100%

Jennie,

I'm on vacation right now so I don't have the ability to examine the
wireshark dump. However, here's a diagnostic query: is your subnet mask set
to 255.255.255.128 /25 or greater? If so, then x.x.x.127 addresses are in
fact broadcast addresses for their subsets. See for reference
http://spazioweb.inwind.it/mydivx/netmask.htm.

Please check.

Regards,
John
