Hi,

I am working on a project that uses TCP 4.0.0 Zynq port. I have one network interface and two endpoints. After called FreeRTOS\_IPInit\_Multi() function, is there any way to change ip address of one of the endpoints?

Thanks

Hi @emrecntz,  
If you’re using DHCP/DHCPv6, the IP address is dynamically changed by DHCP communication with server. But if you’re using static configuration, you can refer to [this post](https://forums.freertos.org/t/freertos-tcp-4-0-0-what-is-the-proper-way-to-change-end-point-settings/18148/7). In short, there is no existing API for users to change static setting dynamically. But users can implement one by themselves.

Note that you need to call `FreeRTOS_NetworkDown()` to re-init the whole stack.

THanks.

Thanks for this solution.
