Using anycast ip address instead of domain name

Greetings, many users including me have problems at the initiating stage of DoH:

1. When local DNS blocking dns.nextdns.io;
2. When local DNS is out of reach, e.g. combining with a VPN service.

This is especially a problem after the Ultra-Low-Latency feature. To solve this once for all, I recommend using a anycast ip with tls cert (like https://1.1.1.1) instead of the domain name dns.nextdns.io in any case or at least for the initiating stage of Ultra-Low-Latency.

If you decide to adopt this only for Ultra-Low-Latency, there's even no need to buy a tls cert for your ip. You can just use a self-signed cert and pin it into your apps :)
