Hi,
is it possible to programatically get the list of a router's all LAN
and WLAN mac addresses. if u know any windows API / library / any
code/ Link... anything... that would help me a lot!

Secondly, i want to get any unique thing in the router. it should be
unique in the world. probably serial no, or anything else...
( programatically. )

i thought of getting UPnp device # of router, and in case of bonjour
routers, get Bonjour device#. But older routers won't support any of
these. That's what i think, please correct me if i'm wrong.

Thanks a lot.. any help is appreciated.

The MAC address should be unique.
 
Hi
Router is a general word, which type and level of performance you are
talking about.
Depending on the Router, it usually has one core IP and one MAC address.
Entry Level combination units (like Wireless Cable/DSL Router) might be
associated with more than one IP and MAC.
If you are talking about MAC and IP of work station that are connected to
the Router. Each Router has it own system to provide it, and what
programming you would like to do have to fit the specific category of
Routers.

Sure. If your router is running a real operating system, just run:
arp -a

For example:
dellbert (192.168.1.11) at 00:02:B3:1E:39:ED [ether] on br0
xxxxxx (63.249.85.1) at 00:10:67:00:D0:9B [ether] on vlan1
micron (192.168.1.113) at 00:0F:66:14:E5:4B [ether] on br0
dellinquent (192.168.1.50) at 00:40:05:C7:1C:44 [ether] on br0
dellicious (192.168.1.51) at 00:C0:A8:7F:FE:92 [ether] on br0

Hmmm... it doesn't list the LAN side IP address of the router
(192.168.1.1) but that's already known because you can't get the arp
information out of the router without first knowing the router's IP
address.

I guess we have to use ifconfig, which results in something like this:

br0 Link encap:Ethernet HWaddr 00:14:BF:B9:10:13
inet addr:192.168.1.1 Bcast:192.168.1.255
Mask:255.255.255.0

br0:0 Link encap:Ethernet HWaddr 00:14:BF:B9:10:13
inet addr:169.254.255.1 Bcast:169.254.255.255
Mask:255.255.0.0

eth0 Link encap:Ethernet HWaddr 00:14:BF:B9:10:13

eth1 Link encap:Ethernet HWaddr 00:14:BF:B9:10:15

lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0

vlan0 Link encap:Ethernet HWaddr 00:14:BF:B9:10:13

vlan1 Link encap:Ethernet HWaddr 00:14:BF:B9:10:14
inet addr:63.249.85.127 Bcast:63.249.85.255
Mask:255.255.255.0

Sorry. I are not a programmist and don't know anything about
programming.
Secondly, i want to get any unique thing in the router. it should be
unique in the world. probably serial no, or anything else...

The MAC address of the router is unique.
i thought of getting UPnp device # of router, and in case of bonjour
routers, get Bonjour device#. But older routers won't support any of
these. That's what i think, please correct me if i'm wrong.

If this is some kind of copy protection scheme, methinks you will need
something more sophisticated. MAC addresses can be spoofed, forged,
or cloned.
