I am a bit confused by DNAME's
I had used them before but I may have used them wrong.
On windows 2008r2 I have some zone's where I create a DNAME for the
root and point it to an A record.
IE:
zone bla.bla
SOA <standard SOA>
NS <mydns>
DNAME www.bla.com
where www.bla.com is an A record.
the reason I was doing this is because www.bla.com has a dhcp assigned address
and I want bla.bla to always point to it.
windows dns does not allow a cname at the root of a zone.
as of 2012r2 with updates this no longer works.
So I decided to see what bind would do with DNAME If I tried a similar
experiment
I have a db.self file I used when I want certain outside addresses to
point back to my inside addresses.
my db.self file looks like so
$TTL 3D
@ 1D IN SOA ns jeffsadowski.gmail.com. (
2017081201 ;
3H ;
15 ;
1w ;
3h ;
)
@ IN NS ns
ns IN A 192.168.1.252
@ IN A 192.168.1.252
And I wand similar for my DNAME so I created db.dname that looks like so
$TTL 3D
@ 1D IN SOA ns jeffsadowski.gmail.com. (
2017081201 ;
3H ;
15 ;
1w ;
3h ;
)
@ IN NS ns
ns IN A 192.168.1.252
@ IN DNAME methanemaker.mooo.com
then when I try and start bind I get error messages like so
Nov 17 09:55:53 methanemaker bash[7049]: zone bla.bla/IN: NS
'ns.bla.bla' is below a DNAME 'bla.bla' (illegal)
Nov 17 09:55:53 methanemaker bash[7049]: zone bla.bla/IN: not loaded
due to errors.
I tried without the NS likes and I get this message
Nov 17 09:48:36 methanemaker bash[4872]: zone bla.bla/IN: has no NS records
Nov 17 09:48:36 methanemaker bash[4872]: zone bla.bla/IN: not loaded
due to errors.
If anyone has a better idea how to map to a dhcp addressed machine
from a zone I'd like to know?
I don't want to recreate the entire superdomain for just one record
that needs changed
IE:
the super domain is managed by an outside service. I don't want to
keep a second copy inside that has a few with different records.
