Hello,
I'm trying to run a local caching-only nameserver (bind-9.3.3) on Linux
in order to bypass my ISP's name-servers, and most things work fine,
except some domains behave strangely.
For example, forecast.weather.gov has a TTL of 5 seconds.
My initial look-up works correctly, and the

Hi Ray,
I'd recommend not using type 'any' in your tests - the results won't
always be what you expect. ANY is a diagnostic query type - and what a

Is there something in the world know to be exactly 4096 or are you suggesting I
somehow craft a record of that size?

I posted a note just before this so not sure if you saw that.
In that I noted my set of EDNS seemed to be contra-indicated as default
is 4096. Setting it to the lower value worked to set advertised value
but in turn the lower value reduced again so it seems one would never be
able to advertise
All,
There has been quite a bit of FUD bouncing around the net regarding the
May 5th signing of the root zone and the sky falling (or at least
massive failures across the internet). I have been asked multiple times
about how I was going to prevent the internet from collapsing for my users.

Why would I set it to 3843? Wouldn't I want it to be set to 4096 even if
