Expose DNS to third party programs

[bibi21000]

Hi,
As my enc28j60 is dead, I continue my devs on the w5100.
I've translated any include names and i'm facing a problem :
I can't access to the Dns client outside of UIPEthernet.
I move it from utility into main directory and update the references, and it works fine.
In Ethernet official, the DNS client is available.
Hope this help

moving Dns and Dhcp from utility to library root would do the job, wouldn't it?

[bibi21000]

yes it will
That's what I've done.
