    I have two zones configured in a view. The forward zone works without issues, changes are also working. However the reverse zone don't seem to play at all, have tested various configurations, see below. Restarted bind, looked for errors or logs and found only this request logged by syslog.

    2022-05-03T22:08:38+02:00 May  3 22:08:38 10.101.0.1 named: queries: info: client @0x80709af60 10.101.16.104#60199 (7.16.101.10.in-addr.arpa): view Site101: query: 7.16.101.10.in-addr.arpa IN PTR + (10.101.0.1)
    

    Query is received but not matched, any help is so appreciated🙏

    Bind version 9.16_11
    Pfsense+ 21.05.2-RELEASE

    Reverse zone
    Zone Name: 1.16.101.10
    Zone Type: Master
    View: Site101
    Reverse Zone: Checked
    Name Server: 127.0.0.1
    Base Domain IP: 10.101.16.1
    allow-query: localnets (Has my internal CIDR blocks configured)

    I've tried two different formats of the PTR record, the default in the UI
    <host> IN PTR <ip_address>
    And
    <last_octet> IN PTR <fqdn>

    $TTL 43200
    ;
    $ORIGIN 1.16.101.10.in-addr.arpa.
    
    ;	Database file 1.16.101.10.DB for 1.16.101.10 zone.
    ;	Do not edit this file!!!
    ;	Zone version 2651606715
    ;
    @	 IN  SOA 127.0.0.1. 	 zonemaster.1.16.101.10. (
    		2651606715 ; serial
    		1d ; refresh
    		2h ; retry
    		4w ; expire
    		1h ; default_ttl
    		)
    
    ;
    ; Zone Records
    ;
    	 IN NS 	127.0.0.1.
    hass01 	 IN PTR  	10.101.16.7
    
    
    ;
    ;custom zone records
    ;
    3 IN PTR nas01.intra.mydomain.local.
    7 IN PTR hass01.intra.mydomain.local.
    106 IN PTR SonosZP.intra.mydomain.local.
    
    

    Forward lookups look like this

    nslookup hass01
    Server:		10.101.0.1
    Address:	10.101.0.1#53
    
    Name:	hass01.intra.mydomain.local
    Address: 10.101.16.7
    

    While reverse fails

    nslookup 10.101.16.7
    Server:		10.101.0.1
    Address:	10.101.0.1#53
    
    ** server can't find 7.16.101.10.in-addr.arpa: NXDOMAIN```
