I don't think so, nor does it seem to make sense to me that you would 
want such a thing (in the general case, you may have a use-case).


SRV records are more than just pointers to a specific server, there is 
also the priority and weight that need to be considered at the 
application level.

srv lookup in record

2020-08-21 Thread Marc Roos


Is it possible to use srv lookups, like eg cname. I do not want to 
create SRV record, I just want to 'get' the ip addresses, that I would 
get vai srv lookup.

Say I have this task

[@temp3]$ dig +short server.test.marathon.mesos
192.168.123.101
192.168.124.50
192.168.124.52
192.168.124.51
192.168.123.100
192.168.123.102

[@temp3]$ dig +short srv _http-apps._server.test._tcp.marathon.mesos
0 1 31024 server.test-usbzr-s3.marathon.mesos.
0 1 31852 server.test-z9x84-s3.marathon.mesos.
0 1 31790 server.test-k7g8r-s4.marathon.mesos. 

[marc@os0 temp3]$ dig +short srv 
_http-demo._server.test._tcp.marathon.mesos
0 1 31791 server.test-c8g8b-s4.marathon.mesos.
0 1 31025 server.test-wtbza-s3.marathon.mesos.
0 1 31853 server.test-d0x87-s3.marathon.mesos.

I would like to only make available the ip addresses that are in the 
same range. If I would use a cname like this:

server.local.   CNAMEserver.test.marathon.mesos.

I would get 6 of which 3 ip addresses are not in the same range. So I 
need to have something like

server.local.   ???  _http-apps._server.test._tcp.marathon.mesos.

Is this possible in bind-9.8.2-0.68.rc1.el6_10.3.x86_64?

9.11 -> 9.16 via COPR

2020-08-21 Thread John Thurston

We're happily running the BIND 9.11 ESV on CentOS 7 by way of:
  isc-bind-esv/x86_64   Copr repo for bind-esv owned by isc

The roadmap I recall indicates 9.11 will move to "security only" updates 
at the end of 2020, at which time 9.16 is slated to become the ESV. I 
figure it is time for me to get a 9.16 instance running and see what 
will be involved in making it work for us.


My questions are two:
A) How will the upcoming change in ESV-designation appear to users of 
the COPR packages? Will there come a time when the repository/package 
"isc-bind-esv" will just deliver 9.16 rather than 9.11?


B) If I have a host currently using "isc-bind-esv/x86_64", and I want it 
instead to use "isc-bind/x86_64", what's the suggested process? Do I 
"yum remove", replace the "bind-esv" repository with "bind", and "yum 
install"? Is it simpler than that?

Re: Error "Query section mismatch : got"

Because when I was from a server that was querying the reverse record
250.199.212.125.in-addr.arpa it gave an error with the "SERVFAIL" error
code so I tried to query directly to the hosting that managed it to
determine the cause.


your query of course makes sense under there curcumstances.

But delegating /24 subnet using RFC2317 delegation is useless, because in
fact you can delegate whole /24 directly

Presumably because they don’t know that APNIC can delegate the /24s that
make
up the /17 independently of each other.
