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

[Frédéric Bernon]

Follow-up Comment #87, task #7017 (project lwip):

>It's analogous to /etc/hosts on Unix (or the 'hosts' file on windows,
although I can never remember where it lives).

yes, of course, I understood

>It can be used for fixed addresses that won't change and are important (some
sort of main server). This can be a) to save delay and network traffic by
having to look them up repeatedly; but more importantly, b) to reduce the
chance of problems when there are temporary DNS lookup failures, at least for
contacting these important servers.

Having something like a "hosts" file could be interresting, but this is the
"hardcoded" side of your patch which cause me a "problem". A "dynamic"
solution should be better (to let the user to complete the hosts table).
