[Pdns-users] Reverse lookups

I'm really confused.  It appears since I've switched to Power DNS reverse 
lookups are failing for my domain and I can't figure out why.   Forward 
lookups are working perfectly.

I've created a new domain in DNS (using PowerAdmin) named 
108.224.199.in-addr.arpa   Within this domain I have multiple PTR records. 
 One looks like this

name: 38.108.224.199.in-addr.arpa 
type: PTR
content: www.luzerne.edu
ttl: 3600

I also have a domain named luzerne.edu containing the equivalent A record:

name: www.luzerne.edu
type: A
content: 199.224.108.38
ttl: 3600

When I do a DIG against my name server and perform a forward lookup 
everything looks great:

;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 36401
;; flags: qr aa rd; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;www.luzerne.edu.               IN      A

;; ANSWER SECTION:
www.luzerne.edu.        3600    IN      A       199.224.108.38

When I perform a reverse lookup using DIG:

;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 54805
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0

;; QUESTION SECTION:
;199.224.108.38.                        IN      A

;; AUTHORITY SECTION:
.                       10800   IN      SOA     A.ROOT-SERVERS.NET. 
NSTLD.VERISIGN-GRS.COM. 2003090400 1800 900 604800 86400

;; Query time: 51 msec

No answer section :(

I know I'm messing up something, but I can't find my error.  Any 
suggestions would be appreciated.

Thanks,
Bob
