Machines on your local network would be able to use a fixed hostname in the web
browser to connect to the Rabbit. I haven't used that version myself, and
I also have a copy of another implementation that an engineer from Argentina
sent me 3 years ago.

Once you have moved to static the router will usually know that the address
cant be assigned for dhcp use, ive done this on implementations before.
with regard to the local network host name working with mobile devices i
dont think it will unless you have some control over dns in that network to
point it at your device. or use dynamicdns to store a local ip that only
works locally

Most DHCP servers can be configured to associate an IP address with a fixed MAC
address so your rabbit would always get the same IP.

Take a look at http://rabbitlib.sourceforge.net/ -- it includes support for the
Windows NetBIOS protocol, which I assume includes NBNS name resolution.
Machines on your local network would be able to use a fixed hostname in the web
browser to connect to the Rabbit. I haven't used that version myself, and
I also have a copy of another implementation that an engineer from Argentina

If you want to allow connections from across the Internet, it's necessary
to configure your router/firewall to forward connections on the public IP
address to your internal Rabbit. The Rabbit may need to learn its public IP
address (I think recent DC 10 releases have an HTTP client sample that does
that) if it includes that IP in any of the web pages it generates (like a page

It works fine. Clearly you've not done it. See RFC 2131 and handling the
DHCPDECLINE message:
4.3.3 DHCPDECLINE message
If the server receives a DHCPDECLINE message, the client has
discovered through some other means that the suggested network
address is already in use. The server MUST mark the network address
as not available and SHOULD notify the local system administrator of
a possible configuration problem.
Maybe the Rabbit software doesn't support it, but DHCP does if it were
implemented.

Hi Phil... with your approach, would the rabbitweb have the same IP Address if
the router was to reboot? The client/end-user doesn't necessarily know
much about regarding IP Address.

I have used that and it used to work.
Newer versions of windows block UDP data from devices that have not been
explicitly communicated with. So, it won't work unless you add an
exception to the Windows firewall.
Why not boot in DHCP first time and then change the set-up to static ip
configuration once happy with IP assume once the device is installed it
will remain there.
I to would like to implement a host name setup will have to look into how
windows achieves this.

Thanks guys for the great solution but I need a solution that would be seamless
to the client/end-user. So I think I'll have to implement a udp server
along with my http server. The UDP server would respond to broadcast messages
from the client with its IP Address, Mask, default gateway. The client will
need to send this broadcast before it communicate with the HTTP server. I hope
this is the most practical solution.
