A good default IP address

embeddedethernetip addressnetworking

My company makes Ethernet devices. These devices have very little I/O. No keyboard, no video output. When the customer gets the device he must configure it for his network. I'd like to choose an IP address that won't conflict with an existing device on his network, but his network could be anything.

Some customers has 192.168.x.x networks. Others have 10.x.x.x networks.

Most network equipment (routers in particular) ship with 192.168.x.1. But this is not a router, so I don't want to default to a low IP address as this will have a higher probability of conflicting.

What is a good IP address to ship with a product? Are there semi-private/unused Class C networks?

Let it be assigned by a DHCP server? if not I would suggest using 192.168.0.250. But DHCP is definitely preferred
