Can’t disable IPv6 on LAN interface because of Router Advertisements Server

[DominikHoffmann]

On my LAN interface, I cannot set the IPv6 Configuration Type to “None.” When setting the configuration to that, I get a notification saying:

The Router Advertisements Server is active on this interface and it can be used only with a static IPv6 configuration. Please disable the Router Advertisements Server service on this interface first, then change the interface configuration.

What purpose does the Router Advertisements Server serve? If I don’t use IPv6 on my LAN, can I simply disable it?

Yes, just disable it if you're not using IPv6.
