This was noticed In networks which use split-view. For example may resolve to when connected to the Internet via mobile network (2G/3G/4G). While on a local WLAN it may resolve to

When changing connection from mobile network to WLAN the public IP address is resolved regardless of what the internal DNS server provides.

I don't think the cache should be flushed when the network is switched to another. You should make sure that you use low enough TTL for your DNS records.
