Hi,

I have some troubles in resolving my local domain.

(I don't know if it is important, but I use DynDNS as DDNS service which 
is synchronized by my router.)

I can successfully resolve local boxes in my own network as well as 
global domains:

  $ dig loki +short
192.168.1.104

$ dig google.com +short
142.250.72.142

But my domain does not resolve:

  $ dig prager.homeip.net

; <<>> DiG 9.16.1-Ubuntu <<>> prager.homeip.net
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 7890
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1

;; WHEN: Thu Aug 19 08:50:03 PDT 2021
;; MSG SIZE  rcvd: 46

When I try this from a system outside my own network (e.g. AWS) it does 
resolve:

$ dig prager.homeip.net

; <<>> DiG 9.11.4-P2-RedHat-9.11.4-26.P2.amzn2.5.2 <<>> prager.homeip.net

Here is my dnsmasq.conf:

domain-needed

server=8.8.4.4
server=1.1.1.1

listen-address=127.0.0.1

# my boxes
dhcp-host=3c:15:c2:d4:45:72,loki,192.168.1.104,12h

Can someone assist me please on what I am missing?

Thank you for your help,
