strange connection? can someone help?

[Mat77]

I use Padavan´s Firmware an can see my connections. Everytime I check my Connections I see:

udp connection:
Source 10.104.128.1 src port 67 Destination 255.255.255.255 dst port 68

I read about the connection to port 68 is related to dhcp.
But I have no Device with this IP?

my internal adresses are 192.168.1.x

I have the Asus Router behind a Motorola Surfboard Modem. Is it possible that it has something to do with my Motorola Modem? If I ping this IP the ping jumps up and down - 8 ms the lowest 33 ms the highest...

The 10.x.x.x address is also a non-routable address. There might be some device (cell phone, printer, computer, TV, etc.) on your network that has that address preset in it.

Click on it's MAC address. You might be able to determine who's the manufacturer of the NIC, and determine which device it is.

I can´t see the mac Adress. And on the tab "Network map" there I can´t find this IP adress. Only in "system log"/connections I can see it.

at the moment no cellphone or printer is here. Only my computer my asus Router and my Motorola Modem.

On my Motorola Modem there is an option of "enable dhcp" if I disable it and restart my Modem - nothing changed. How can I get the MAC Adress for this device?

The modem's MAC address should be written on a sticker.

I suspect that 10.xxx.xxx.xxx is simply the IP of your ISP's DHCP server. Cable providers tend to use this IP block for some of their routing equipment - mine does. It might come up if you do a traceroute to any remote host. For example, here's what my ISP uses:

Tracing route to www.google.ca [173.194.43.87]
