That is just letting you choose which address to connect to - your mikrotik device has an IPv4 and IPv6 address bound. Just choose one - they both go to the same device.

but i havent ipv6 in my routerboard

winbox shows that you do.

can you please tell me
what is the ipv6 and how i can disable it (i made hotspot and dhcp server and interfaces)

Regards

Go into the menu “System → Packages” and disable the IPv6 package:

IF I DISABLED IT IT WILL MAKE MY ROUTER BOARD WITHOUT PROBLEMS IN hotspot and dhcp server

what about this problem

5.19 is not released yet. And you where asked to post “/tool profile” output so we could see at least something of what is happening on the router.
