host name DNS entry

['chris']

hi

I've setuped an external DNS server.
Howto find a slave server for my new server?
How should be host name DNS entry for my new server on the slave server?

I don't understand your question.

¿You configured a primary dns server and you want to configure a secondary DNS server?

I've setuped primary (Master) DNS server.
Howto find a Slave server for my Master server if my ISP is not agree?
How should be DNS host entry for my new server on the Slave server?

>>> Howto find a Slave server for my Master server if my ISP is not agree?

Again, I don't understand what means "my ISP is not agree".

>>> How should be DNS host entry for my new server on the Slave server?

As your questions are still confusing to me, let me explain a little how it should work.

You configure a primary DNS server which is reachable using a public IP address.

If you want a secondary DNS server, this should also have a reachable IP public address.

You configure your zones, one type master and one type slave pointing to the master IP.

And resource records should look like this:

IN NS dns1.domain.com
IN NS dns2.domain.com

Then, you need an A record for both:

dns1 IN A 11.1.0.1
dns2 IN A 11.1.0.2

I've setuped public DNS server, it's on the internet unknown, because I need DNS host entry for this server.
I don't have a Slave server and try to deal with ISP to setup my host entry -> myhost.domain.net on their DNS server, but it seems to be difficult.

Yes. You must request your NS public IP to be added to your country domain name registration services.

>>> I don't have a Slave server and try to deal with ISP to setup my host entry -> myhost.domain.net on their DNS server, but it seems to be difficult.

My question is:

- Your ISP holds your primary DNS server, and you configured a slave, and are you requesting your ISP to add the record for your secondary DNS server?

or

- You hold your primary DNS server, and you are requesting your ISP to be a secondary DNS server

or

- You configured a primary and secondary DNS server, and you are requesting your ISP to register both?

I have primary DNS server, and I'm requesting my ISP to be a secondary DNS server.

[Ivan Ferreira]

Then you only need to add an NS an A record on your primary DNS server, and set the allow-transfer option for your zone.

But, if your ISP refuses to be a secondary DNS server, you don't have many options.

It is very common to set up DNS servers to only permit update based on IP address.

I did this while setting up global DNS for nds.com I did not want DNS servers using these servers for work other than I designated them. So only IP addresses I configured into named.conf were permitted to download updates and zone records.

A certain level of cooperation is needed to make a slave DNS server work. Many ISP's to avoid DNS cache poisoning and other abuses set up strict rules on DNS information exchange.

You need fixed IP addresses and cooperation from the ISP to make this work.

Thx a lot for all answers.
I'm really lucky, my ISP was agree.
We've setuped a Slave zone on the DNS from my ISP and it works well.
