[lwip-devel] [task #7017] Implement DNS client

[Jim Pettinato]

Follow-up Comment #10, task #7017 (project lwip):



Looks like I'll be winding up the final test/release soon on the product I'm
working on here at the office, and so I'll have some time to work on this...
Kieran, feel free to assign this to me and I'll tackle some of the issues
mentioned in the comments and get it in a state suitable for integration.

(I'll need CVS write access, btw..)

Things I plan to address:

 - change module name to dns.c - and prefix all exported 
   functions with dns_xxxx
 - check all return values from other lwip functions and handle
   appropriately
 - periodically expire entries (check RFC for default time?)
 - changing default #define of MAX_NAME_LENGTH to RFQ 
   recommendations with ability for end user override in 
   LWIPOPTS.H.
 - send initial request immediately instead of waiting
   for timer if a query is required
 - secondary server support
 - Initializing state table to UNUSED instead of DONE
   (and testing that)
 - testing compressed answer expansion

Did I forget anything??
