I'm not using this DNS for all my connections (when I'm connecting
through my college I'm using its DNS), but when I use 135 I do use it
- 135 has many providers and each has its own DNS, and it would be
tiresome to look for the DNS and update resolv.conf to use it each
time I'm using another ISP from 135. Since neither I nor other people
(I suppose) use 135 for their regular access, but only occasionally,
it doesn't hurt HUJI's DNS too much. The moment I hear otherwise from
HUJI I'm stopping doing it. Can anyone from HUJI respond?

As Ze'ev said this feature is not part of the standard IPCP, but
something that Microsoft added themselves. Linux's pppd can supply
this information if it acts as a server for a Windows machine (via the
ms-dns option), but it cannot receive that information and use it from
another server. It would be very hard to implement such a thing,
actually. Receiving DNS addresses and making the machine use them
means modifying /etc/resolv.conf. And what if the machine is running a
forwarding name server? Then it's /etc/named.boot you need to
modify. pppd can't know and can't be taught all that.
