Re: [lwip-users] 2 different network number

[Bernhard Wiegel]

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
