DNS Server not working

Hello,
I bought a CRS125-24G-1S-2HnD-IN and have troubles getting DNS working.

I added a static DNS entry:

[admin@RouterOS] /ip dns static> print 
Flags: D - dynamic, X - disabled 
 #    NAME      REGEXP        TYPE     ADDRESS                           TTL         
 0    P-099                            192.168.88.10                     1d

And this is my DNS server configuration:

[admin@RouterOS] /ip dns> print 
                      servers: 
              dynamic-servers: 10.180.2.20,10.160.2.20,10.170.2.6
               use-doh-server: 
              verify-doh-cert: no
        allow-remote-requests: yes
          max-udp-packet-size: 4096
         query-server-timeout: 2s
          query-total-timeout: 10s
       max-concurrent-queries: 100
  max-concurrent-tcp-sessions: 20
                   cache-size: 2048KiB
                cache-max-ttl: 1w
                   cache-used: 49KiB

My windows 10 machine cannot resolve the host P-099:

nslookup p-099
Address: 192.168.88.1
can’t find p-099: Non-existent domain

What I am doing wrong?
Is there somewhere an example configuration for DNS?

best regards,
Wolfgang

I found the problem: I have to add ‘ping P-099.’ at windows terminal, and then it is working. The dot is important.
