we have lots of internal extra zones on our dns for development overrides.
I came across RPZ in bind, which looks interesting to us because we could drop tons of extra zones and put everything in a rpz-development-override zone file.
I tried RPZ and i can successfully put in an A record or CNAME pointing to "any" IP or FQHN.
We use lot`s of CNAME aliasses for server virtual host name aliasses, i.e.
myserver IN A 126.96.36.199
myserver-vhost1 IN CNAME myserver.
myserver-vhost2 IN CNAME myserver.
myserver-vhost3 IN CNAME myserver.
How can we do that with RPZ ?
Apparentyl I can use A records and CNAME in RPZ zone file, but as soon as i create a CNAME which points to an A-record within the RPZ Zone file, it doesn`t resolve :
www.this-is-a-test.de CNAME www.google.de.
www.this-is-another-test.de A 188.8.131.52
www.this-doesnt-work.de CNAME www.this-is-another-test.de.
# nslookup www.this-is-a-test.de
www.this-is-a-test.de canonical name = www.google.de.
# nslookup www.this-is-another-test.de
# nslookup www.this-doesnt-work.de
** server can't find www.this-doesnt-work.de: NXDOMAIN
