Hi,
Thanks. I will have a look at it. I bought this netgear wireless adapter that
does this and traced the packets with Wireshark. It was a DNS query from the PC
and then a reply from the device. 2 packets at most but I need to investigate
further.
Regards,
Nick

Hi Nick,
If you connect direction a PC to the embedded system, unless your PC is DHCP
server, your board won't get an IP. What i would use in your case is AUTOIP
(this is supported in lwip). Then, in order to address your board using DNS
names, again, if no DNS server is available on your PC, i suggest you to have a
look at multicast DNS ( this one is not currently supported in lwip AFAIK,
you'll have to develop it).
Both of these standards are part of Zeroconf suit, you may be interested to
have a look...
regards,
Bastien

Hi,
This is the situation: User connects PC to embedded system. And to access it
instead of typing in an IP the user types in a domains name.
I have setup my embedded device to use DHCP. I would like to when a user
types in a domain name of : www.mydevice.com the dns query should return the
devices IP.
How can I map a domain name to an IP?
Regards,
Nick
