It's been suggested that a new network number would need This is legal. The answer is different depending upon what type of net you are running. From the net address 128.115.26.0, lll-labnet (128.115), you need only pick up a new *sub* network 128.115.27 ?? from your local net administrator. This is because your particular network is a class B net. If your particular lab is to be isolated to 128.115.26, you could experiment with a different subnet mask, say 255.255.255.127. If you chose this method, the 8th bit of the host address would determine whether you are on the slip network or not. Example: 128.115.26.10 local ethernet 128.115.26.137 Slip ethernet (127+10) >- What needs to be in the routing table for SLIP interface B (Machine B)? > It seems that it needs a default address to get out, but is there any more?

You could think of doing proxy arps as an alternate. Either method (subnet vs proxy arp) should work. Personally, I think the subnet mask is a much more efficient method of doing things.
