when i dumpdb from the cache dns, some domain's ns records are glue
DNS, and others are authauthority.
The TTL are different. which type is used in Cache DNS?

I got some bind servers doing iteration resolution, and return the
results to users. But I found that some names got too big TTLs, whose
RRs can not be replaced correctly by new RRs in time. This leads to
user‘s blame, we have to flush the caches by hand, and

Many ISP's caching DNS servers do this stuff.
AFAIK there is not such an option for that, but you can do it from
BIND's source.
max-cache-ttl ?
Thanks Cathy for pointing out that.
From what googled:
Hello,
Please see this case:
$ dig funnygamesite.com @k.gtld-servers.net
; DiG 9.7.3 funnygamesite.com @k.gtld-servers.net
;; global options: +cmd
;; Got answer:
;; -HEADER- opcode: QUERY, status: NOERROR, id: 35540
;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 2, ADDITIONAL: 2

I was thinking why RFC requires the values of MX and NS must be hostname
not IP.
Any glue? Thanks.

My question:
Is there any possibility in Bind to give a quoata to a client? e.g. that from a
given IP no more than houndred queries per second are allowed and the rest is
to be blackholed.
That way only the client causing the load would have a problem but

Just out of interest, why wouldn't you just comment out the zone stanza?
Would cut down on memory usage, load time, etc…
I'm sure you have a use case, just a wondering…
Well, my dns manage system (dnsbed.com) requires a zone pause feature.

Hi,
If I just want to disable any client to query for a zone, but keep that
zone in the config file (maybe later I will enable it to be accessable),
can I just set:
allow-query { none; };
in the zone section?
zone example.com {
type master;
file example.com.db;
allow-query { none; };

I remember there is a rndc option, but not sure.

Hello,
Once I changed the IP address for NS records, for example,
example.com. IN NS ns1.myzone.com.
example.com. IN NS ns2.myzone.com.
I changed ns[1-2].myzone.com to new IPs in myzone.com's DNS, then how to let
BIND for example.com to know the NS has been changed?
Thanks.
Hello,
My second nameserver has tow IPs, for example,
61.144.56.1
61.144.57.1
(They are in different CIDRs.)
and my ns2.example.com was pointed to these two IPs.
Will this cause problems, for example, the duplicated notification or
zone-transfer?
Thanks in advance.

Hello,
The querylog of BIND in my hosts is like:
client 58.240.56.18#16768: query: s18.mhxx.game.yy.com IN A -EDC
For the last part, I know the '-' means non-recursion,'E' means EDNS.
But what are the 'D' and 'C' flags?
thanks.

Thanks michael.
That's right for me.
