Antwort: RE: How to delete dynamic DNS cache (bind 4.9.4)?

[Kevin Darcy]

What are you talking about? kill -9 kills the process unconditionally; any
cache entries it had in memory are gone. So you must be using "cache" in
some different way. When the nameserver starts up again, it'll use the hints
file to query the root servers (unless it's a forwarding nameserver) and it
will load authoritative data (master and slave zones) and the contents of
stub zones. That's *all* it knows about before listening for queries. Are
these "internet resolved hosts/domain" you're talking about coming from the
hints file or from authoritative data or stub zones perhaps? That would
explain why kill -9 doesn't "reset" them.
