Hi, all,
thank you very much for discussion. It was interesting and very useful.
You can pretty well imagine that I am not much dns involved,
I am rather unix and unix HW guy.
Unfortunately I saw dns cache poisoning attack and although it could be
provoked by side effects it's better to get rid of it altogether.
For just 14 (241-254) addresses it is not difficult to maintain 2 types
of master zones in sync (RFC 2317 and RFC 1035) and it's enough to put a
couple of comment lines to not forget it later.
Yes, life is short but this is not the reason to not train the brain,
can help to hook a life a bit longer ...
Bring stir to the chicken coop and request compliance is generally
good idea and fingers itch but I don't expect much from our ISPs ...
So first I'll try "type forward" within a view,
then I'm sure, one address zones can serve me right.
I will also contact the ISP but without great expectations.
Why I do all this is:
- enforce security
- assure stable mail exchange (which depends on reverse resolving)

That's great locally, but it doesn't match the 2317 delegation from the
upstream, and usually it's not possible to change what they send you.
Or are you suggesting maintaining both the individual versions of the
zones, and the 2317 zone?
No. I'm suggesting that they tell their ISP to do RFC 2317 right
or do RFC 1035 delegations. If their ISP won't do either change
ISP.
Doug
