DNS issue

Hi,

 

We have observed that the DNS server is failing to resolve the IP address. This is mostly seen when we switch the router OFF/ON. But that time we can ping the DNS IP successfully. Note that other devices are working in the same network without issues. Please provide a solution.

 

Another question is should we start DNS client when we retrieve IP from DHCP server? We are using the below calls to get IP from DHCP server.

ipcfg_bind_dhcp_wait(),

dnsIPAddress = ipcfg_get_dns_ip(ENET_DEVICE,0)

 

Should I call ipcfg_add_dns_ip(ENET_DEVICE, dnsIPAddress ) after ipcfg_get_dns_ip()??

 

More details:

OS                     : MQX 4.0.2

Platform            : K60

Regards,
Arya

Hi Arya:

I would suggest you refer to MQX 4.2.0  and patched 4.2.0.2. In this version, we fixed one DNS bug, it seems related your issue.
