Question

Domain delegation

by Sep 6, 2016 3:27AM PDT

I registered domain say `abc.pl` at registrar say `registrar.pl`. Recently i've installed & configured bind server on my home computer to host `abc.pl` domain. Now as i understand i have to delegate my domain on my hitherto `registrar.com`. The registrar have a GUI panel with option "external DNS servers" where one can type new DNS servers.
I have some questions about the datails:

1.) Am i right that the registrar updates NS records at the upper domain registrar that is NASK in case of `pl` domains to point now to my home DNS server/servers?

2.) What does he do with the SOA record describing `abc.pl` domain? Am i right that it just updates the record in sth. like that:
The old version (before the delegation):

..
$ORIGIN abc.pl.
@ IN SOA ns1.registrar.pl. root.registrar.pl. (
...
@ IN NS ns1.registrar.pl.
@ IN NS ns2.registrar.pl.
ns1 IN A registrar_dns_1_ip
ns2 IN A registrar_dns_2_ip

The new (after the delegation):
..
$ORIGIN abc.pl.
@ IN SOA ns1.mylocal.pl. root.mylocal.pl. (
...
@ IN NS ns1.mylocal.pl.
@ IN NS ns2.mylocal.pl.
ns1 IN A mylocal_dns_1_ip
ns2 IN A mylocal_dns_2_ip

3.) If i'm right that it should set `AA` a `Authoritative Answer Flag` to `0` to indicate that from now it isn't an authoritative server for `abc.pl` domain?

I'd have to think hard about this along with why and a lot of other questions.

But where you registered this should be asked all this.


I don't see anyone replying to your posts a day later. Maybe you need to reveal what you are doing. That is, NO ONE TODAY WILL DARE USE YOUR DNS. I hope you know why.

Depends on what you have your registrar change.

You can possibly continue to use them as your "Public" DNS and just point the resolution of your domain to your IP.

Or, you can have the registrar indicate that your domain's DNS is at your public IP. That changes the top level DNS to simply refer any request for your domain or sub-domains to your IP and it is your DNS at that IP that will reply with the IP of the requested domain or sub-domain. This doesn't mean that anyone outside your private network will use your DNS for general lookups. And as previously posted, anyone outside your private network would be a fool to use your DNS as a general DNS. But you should also configure your DNS to only reply to public IPs with requests for you domain only. It can be setup to reply to your private network with any request. Otherwise your private network should be configured to use your ISP or Google (8.8.8.8, 8.8.4.4) DNS.
