This is not a "solution" but a hack (IMHO), and it's the thing we talked
about right at the start of this discussion. There are subtle details, so a
bit more discussion before adding this as an optional feature is OK, I
think. Never copy linux implementation and call it design before undstanding
the problem and all possible solutions and their implications! (No pun
intended: this says nothing about either linux implementation or design,
just about the "copy an existing implementation" substituting design work.)

In the concrete example: the setups where I've met the problem always
included some NAT functionality on the ISDN router. Since the local
(caching) nameserver as well as the http-client are (at least logicaly) on
the other side of the translation, a fine tuned integration between the NAT
framework and the IPCP implementation could resolve this problems in a much
cleaner way. At least at first lookt this seems possible.
