DNS not resolving IPv6 address for internal domain although it does for external

smk

Hi
Running pfsense Version 24.11-RELEASE.

Can someone please help me troubleshoot why internal/local domain is not resolving to IPv6, but external domains properly resolve to IPv6:.

Internal domain does not resolve to IPv6, only resolves to IPv4:

nslookup officevm-1
Server: syn-2603-8001-3400-4a00-02e0-edff-fec4-b04e.res6.spectrum.com
Address: 2603:8001:3400:4a00:2e0:edff:fec4:b04e

Name: officevm-1.skubsad.com
Address: 192.168.221.100

External domains resolve to IPv6 and IPv4 correctly:

nslookup microsoft.com
Server: syn-2603-8001-3400-4a00-02e0-edff-fec4-b04e.res6.spectrum.com
Address: 2603:8001:3400:4a00:2e0:edff:fec4:b04e

Non-authoritative answer:
Name: microsoft.com
Addresses: 2603:1030:b:3::152
2603:1030:20e:3::23c
2603:1030:c02:8::14
2603:1020:201:10::10f
2603:1010:3:3::5b
13.107.253.69

Running ISC DHCPv6 server:

Router Advertisement set to DHCPv6 server:

DNS Resolver enabled on IPv6 interfaces:

DHCPv6 leases are showing up, although without hostname:

I'd appreciate any pointers or help.

Thanks in advance.

@smk you may need to include the nslookup parameter -type=aaaa in your query. I believe by default nslookup only returns ipv4 records on most machines.

@Mission-Ghost : Thanks. Same nslookup without -type=AAAA on same machines returns IPv6 for external domains.

Forcing AAAA in nslookup for internal domains, returns this:

nslookup -type=AAAA officevm-1
Server: syn-2603-8001-3400-4a00-02e0-edff-fec4-b04e.res6.spectrum.com
Address: 2603:8001:3400:4a00:2e0:edff:fec4:b04e

***** No IPv6 address (AAAA) records available for officevm-1**
