Hey guys,

I'm currently looking over my webserver code and have the following question:

I never used DHCP, always fixed IP.

What would be the right code to receive a IP via DHCP from my router. Is the following code correct (DhcpEnable ist just a bool I set)

if ( DhcpEnable )		    {			    //Dynamic IP			    interf.EnableDhcp( );			    interf.RenewDhcpLease( );		    }		    else		    {			    //Static IP			    interf.EnableStaticIP(ipAddress, subnetMask, gatewayAddress);		    } 

Greets, Markus

Hi Markus,<br /><br />That looks right. You may not need to do the .RenewDhcpLease() after .EnableDhcp.<br /><br />Also--this will update your network configuration which may fill up the config sector. I would recommend that you only change the IP settings when you need to change them. Otherwise--you can just leave them as-is.<br /><br />Chris
