IP Networking

hi,
i want to know how can i get the ip of the hosts that are directly connected to my computer. for example in picture 1, host A is directly connected to the hosts C, E and B. if i'm working on host A, i want to know how can i get the ip of C,E and B that are directly connected to my host(host A), as you know there are also other hosts in my subnet, like D, F, H and G, but i dont want their ips, because they are not directly connected to my host.

picture 1


thanks in advance.

An ethernet subnet acts like a bus, you don't see "more direct" or "less direct" connections.

I'm not sure how you got a topology like that from a single subnet. Are some of those nodes switches?

it's not exactly the topology that i wanna use! i've drown this picture to show what i want, there are no switches, all the hosts have an ip.
in fact, i want the ips of the hosts that can be used as gateway ip in my host, tell me something, can host H be my gateway? or can i add to my route table another subnet and define host H as the gateway for reaching to that subnet?

still requires some clarification

what kind of clarification do you need?
tnx for answer.

If they're not connected with switches, then what makes the tree shape?

Is it all the same subnet? If not, which subnets are which?

You don't get logical structure inside a subnet. Don't mistake physical structure for logical structure.

This might be a confusion of terms. Maybe list IP addresses for machines and we'll see what you mean by structure.

you'e right, maybe i said it in a bad way, in fact all the devices in the picture are hosts, but if there is more than one connection for a host, it means that there is a switch connected to the host. i didn't drew the switches in the picture, there is only one subnet, all the hosts in the picture belong to the same subnet. if what i say is wrong then i might need more information about subnets.
