I have woring a 28J60 and a ATMega.
Now i want to write the DHCP Client and DNS-query function.
Some want to help me?
DNS is a UDP Packet at 53 port of router's DNS Server.
If you need DNS query means try this site http://www.whoisxy.com/ and also get the ip to domain,domain to ip,ping test,etc......
There's working code available to do both DHCP and DNS requests for the Wiznet. Have you looked at modifying that for the 28J60?
