You can get the IP address, Netmask and Gateway from the netif you're

for the interface: e.g. netif->ip_addr
With this, you are relying on lwIP-internal data structures! While this
surely works, it is strongly discouraged by the lwIP developers: The
internals data structures are never guaranteed to be portable accross
versions so you risk your code being valid for a specific version of
lwIP only!
You also risk reading garbage if, for example, the DHCP client is in the
process of updating the address from a new lease.
