Re: [lwip-users] Network name of device

[Jeff Barber]

In order to create a connection to your lwip device, the client must
be able to translate the host-name to an IP address.  Traditionally,
this has meant teaching the local DNS server that the name "lwip"
translates to IP address X.X.X.X.  The DHCP host-name option provided
by the lwip device can factor into this if the DHCP server and the DNS
server coordinate appropriately.  (However, in the traditional model,
the lwip device is *not* directly involved in the actual
name-to-IP-address translation.)

It is possible to do this without a dedicated DNS server or DHCP
server, but the client host and your device would need to implement
"zero configuration networking" (see
http://en.wikipedia.org/wiki/Zero_configuration_networking as a
starting point).
