Re: [lwip-users] 2 different network number

[Bandu]

Hi All,

 

thank you very much for you answer.

 

Is that mean in LWIP, we need a small routing table ?

 

thanks.

Hello all,

0.0.0.0 will not work at all!

The purpose of the netmask is the separation of the host and the network part of the IP-adress.

Lets make an example: Netmaske 255.255.255.0, IP 192.168.1.23
All leading ones of the netmask  -> adress of the subnet  the machine is located. -> subnet: 192.168.1
The host can be identified with the zeros of the netmask. -> the host part is 23

So the netmask really determines the number of hsts within your subnet.
Do you have more than 253 hosts in your netmask that you need something different than 255.255.255.0 ?

Regards,
Bernhard

"0.0.0.0"....That sounds like something reserved.

   I think that's a good idea.
   How about if i use 0.0.0.0 mask?

           Is there anyway that I can achieve that?

       A subnet mask of ff.ff.fe.00 would do that, or am I barking up
       a different tree?
