isdnutils + dynamic dns (ms-get-dns in ipppd(8))
For everyone who wants to use ms-get-dns with ipppd, here
is my bug-report against isdnutils and the response
I got (from Paul Slootman):

For intermittently connected systems (which is usually the case if
you want to configure DNS via ipppd), I now recommend using dnrd.
dnrd comes with an ip-up.d script that works fine with both ppp and
ipppd. In fact, the new version of ipppd will "Suggest: dnrd".
