BIND/DNS Zone meaning of "IN"

view full story
linux-howto

http://serverfault.com – I have been reading http://www.centos.org/docs/5/html/Deployment_Guide-en-US/s1-bind-zone.html but the document raised a question. What is the meaning of IN? Is it just a class which is optional or does it mean more than that? (Yes I read that in named.conf IN is a class statement but I don't know if the same applies to the zone files) I understand that if I don't define a class "IN" in the named.conf zone statement then I don't have to use it either in the zone files like for example: With class statement named.conf zone "example.com" IN { file "example.com.zone"; }; example.co (HowTos)

Stories similar to BIND/DNS Zone meaning of "IN"

bind mangles my zone file every time a DNS update is done. If defining a block as constant isn't possible, is it possible to have 2 or more zone files describing one domain?

I am doing web development and host the local versions of sites on my machine. I have Linux Slackware 14.0 with BIND 9.9.1-P3. In my named.conf I have this:

zone "localhost" IN { type master; file "caching-example/localhost.zone"; allow-update { none; }; };

In localhost.zone:

$TTL 86400 $ORIGIN localhost. @ 1D IN SOA @ root ( 56 ; serial (d.

After upgrading from Ubuntu 8.04 to 10.04 my DNS isn't working properly anymore.

I keep getting this error when I run named-checkzone example.com /var/cache/bind/example.com.zone.db

zone example.com/IN: NS 'mx002a.example.com' has no address records (A or AAAA) zone example.com/IN: not loaded due to errors.

in /var/cached/bind/example.com.db

$TTL 3D @ IN SOA mx002a.example.com.

Ive set up 2 dns servers. using tsig can someone tell me or direct me to a how to for adding zone to named.conf or named.conf.local file automatically? i mean if i add a zone in named.conf and file of the zone, i want it to be executed in the second server auto. is there a howto? tutorial? any one can direct me or?

I am new to webmin. I have followed https://www.youtube.com/watch?v=rV9x6DVKxHg video tutorial for the setting up name servers.

But my Bind is not working now :( I am getting the following errors . I am using CENT OS .

I'm new to Cloud servers and CentOS so bear with me :)

I'm running a CentOS 6 server on Rackspace Cloud. I've installed Virtualmin 3.89 (GPL version) and most of it seems to be configured and running ok.

When I add a new virtual server i get the following error:

Adding new DNS zone .. .. BIND DNS domain failed!

Hello, I am trying to learn how to set up dns zones with named.

I created a zone (as attached) but I am sure I not written it correctly, because named will not start when it tries to load the zone. I have also attached the error message I received.

Can anyone please tell me how to write this zone file correctly. I am simply trying to create a zone that links 'philParm.com' to 172.16.52.3.

I am trying to build a sinkhole for BIND. I created a master zone file for malicious domains and created a separate conf file, but I am stuck.

I have a list of known bd domains that is updated nightly.

I've followed several tutorials on installing your own nameservers and I'm pretty much at my wit's end, because I cannot get them to resolve. Note, the actual domain and ip address has been changed for privacy to example.com and 192.168.0.1.
