IVPN vpn works with nextdns in ios

In IVPN settings, custom dns, dns adress field , type in https://dns.nextdns.io/ your number at nextdns.com setup somewhere. Maybe without https, hit DOH button, hit enable. There is also an option to enter the same dns adress for dns without vpn connection. Thisis for lan network. Not internet. Because vpn is turned off when using this. The first one above is for internet since vpn is turned on.
