Hello,
I'm not sure, is it right for the management of zone files, with both dynamic
update and editting by hand?

records for a label
where you have a CNAME record (well, with the exception of
RRSIG records
if you're using DNSSEC). This is covered in great
detail in any
introductory text on DNS.

Hello,
like this domain:
blogchina.org
I can't get its NS RR in public DNS:
dig blogchina.org ns @8.8.8.8
get nothing.
But it does work correctly.
for example, query the record:
dig udb.yy.blogchina.org
works!
How to setup Bind for this?
Thanks!

I have a question about the query process of local dns cache to remote servers.

We have been facing this problem, sometime the original server was down, but
Bind didn't know it, and still answered clients with the dead IP.
Or sometime an external domain name has two or more IPs, accessing to part of
them is fast, but accessing to another part is slow.
So, do you

Hello gurus,
Say I have this glue record in parent's DNS:
child.example.com. IN NS ns.child.example.com.
ns.child.example.com. IN A 12.34.56.78

ns.child.example.com..
What will be happened? Does it affect client's query to other

Hi,
Is it possible to set weight for records?
for example,I have these two A records:
wwwIN A 192.168.1.100
IN A 192.168.1.101
But I want 192.168.1.100 take the weight of 75%, and 192.168.1.101 take the
weight of 25%. That means, when clients query for www.domain.com, 1.100
What will be happened if a MX is an numeric IP?
for example,
# dig vip.online2.sh.cn mx +short
10 218.1.71.125.
Thanks.

I'm just not very sure, what's the usage for a glue record?
When an upper DNS returns a domain's authorised DNS server, will it also
returns the authorised DNS server's IP address? So glue record works as this
way?

Hi,
Firstly the DNS serveres for that domain is not mastered by me.
I got the NS dig info as below.
You can see, if I specify another public DNS (211.66.80.161), the results can
be fetched. If I don't specify a DNS (use the default one 202.96.128.143 of my
ISP), dig gets nothing.
