hi ansar,

i'm sorry late reply.

dynamic updates can sent of following reasons or events:

  1. an ip address added, removed, or modified in tcp/ip properties configuration 1 of installed network connections.
  2. an ip address lease changes or renews dhcp server 1 of installed network connections. example, when computer started or if ipconfig /renew command used.
  3. the ipconfig /registerdns command used manually force refresh of client name registration in dns.
  4. at startup time, when computer turned on.
  5. a member server prompted domain controller.

you mentioned issue dns server still have 192.168.1.(wired) range ip record when moved wired connection. maybe try use ipconfig /registerdns command after moving wired connection.

for more details, please refer article below,
