Hello ,
I face the following problem ==> bind do not accept an A record with
underscore:
Example: example_try A1.2.3.4
Same for a PTR:
Example: 1.2.3.4 PTR example_try
Is it absolutely forbidden to have in such cases an '_'?
I know that it is possible for SRV or TXT records
The SRV and TXT records usage is depending on underscore not being part of a
hostname.
The separator in hostname labels is dash. e.g. my-host.example.net
_ssh._tcp.example.net SRV can be safely deployed because there are no legal
hostnames
starting with _ssh and _tcp.
Hostname (and mail domain
Hello,
Thanks for these clarifications.
The issue we face is that a telecom provider ask us to implement a PTR record
with a name like "example_try.net"
We tried this configuration but BIND do not accept it.
The telecom provider complaints we can not make this DNS configuration and that
it must

Matus,
What do you mean with " absolutely no, but since underscore is not valid in
hostname as per rfc1123, I don't recomment you to use it in hostnamed" ?
I tried with the following configuration in zone " dekil.nl " and bind do not
accept it:
hello_mail2.dekil.nl. 3600IN A

point out to that provider it's a bad idea and that they should know that!

substitute the last word with "hostnames" (a mistype).

You are mixing the two things here. If the provider has asked you to create a
PTR record,
why do you ke
Hello,
Indeed my question was on A record but the issue is on PTR record.
I can configure the following line:
_ptr.dekil.nl. 3600IN PTR _81.99-129-109.adsl-dyn.isp.dekil.nl
It workswe can use "_" in both sides.
But what is strange is that the following configuration do n
Hello,
I'm checking the source code of bind dlz since we need to use ldaps instead of
ldap.
I found this on the source code of BIND DLZ:
If (ldap_url->lud_port != 389) {
db->log(ISC_LOG_ERROR,"%s query must not specify a port", msg);
result = ISC_R_FAILURE;
goto cleanup;
}

Hi everybody,
Hi,
Since I'm a little bit desperate with this issue, and after asking

No. The PTR records that map from IP address to hostname enforce the hostname
rules.

Hello.
We are looking to add this to our fleet of bind servers based on:
https://gitlab.isc.org/isc-projects/bind9/-/wikis/DoH/DOH-and-DoT-Design
However, there does not appear to be support for DoH ala bind9.17 atm. Do
we have
a timeline for its implementation?
Cheers.
