RE: [lwip-users] How to determine if DCHP changes the IP address

[Bill Auerbach]

Thank you, great.  I’m glad it’s been done already.

 

No, it’s not in 1.2.0 – not that I see.

Hi,

 

I think you can use the LWIP_NETIF_STATUS_CALLBACK option. Like this, each time netif_set_up or netif_set_down are called, you can be inform, because

dhcp_bind call netif_set_up, and dhcp_release call netif_set_down. Of course, this is in last CVS HEAD code. I'm not sure it's integrated in 1.2.0...

Subject: [lwip-users] How to determine if DCHP changes the IP address

 

Hello,

 

Can someone recommend a good way to get the IP address assigned by the first DCHP acquire?  And on an IP address expiration, if the IP address changes – how can one determine that this has occurred?  If there is not a user function callback to indicate when a setting changes by DHCP, can I recommend this as a future enhancement?

 

Thanks,

Bill Auerbach
