why ethernet addresses are not incorporating in routin tables?

Question

this is regarding networking

Answer 1

What kind of routing tables are you talking about? and there is no such thing as an ethernet address.. Are you talking about IP address, MAC address, what? Routing tables are incorporated in routers and servers, most are just set to dynamic routing though.. On bridges your MAC address is incorporated on a routing table, to check and see if the node is under the gateway instead of over tcp/ip.. Elaborate a little it will get your further..

Answer 2

The term "Ethernet address" is commonly used synoymously with MAC address. MAC addresses are only relevant on the local network segment -- it's a physical layer thing. Therefore there is no need to include that information in routing tables -- a network layer thing.

Answer 3

Your question is a little ambiguous, but if I can make a small assumption I think you are asking about what is a private address versus a public IP address. To truly see what addresses are in any businesses routers, you would need access to them.

Private IP ranges are as follows:
10.0.0.0 through 10.255.255.255
169.254.0.0 through 169.254.255.255 (APIPA only, ignore these)
172.16.0.0 through 172.31.255.255
192.168.0.0 through 192.168.255.255

Any other range is public and should not be used on any private network that connects to the Internet. If you were going to try to connect (via router or VPN) to another establishment you would have to assure that both facilities had different IP subnets (different address ranges) or problems would exist. There are ways to remedy this via the router (NAT) but I'm not sure that this is what you are trying to do.
