Keyword	Description

cloudflare	Use Cloudflare for DoH resolution.

url	Specify the URL of an arbitrary DoH server to use for DoH resolution.

Defaults

Usage Guidelines

This command specifies how DNS lookups are performed by Island.

By default, Island uses DNS over HTTPS (DoH) services provided by Cloudflare to resolve DNS requests. The https option can be used to change the DoH provider to Google or to an arbitrary DoH server.

Island can also be configured to use standard recusive DNS resolution. Both the recursive and the dnssec options enable recursive DNS mode, the difference is that dnssec also enables DNSSEC validation.

If Island is unable to access the specified DoH provider, it will revert to recursive DNS.

Examples

ip dns mode recursive
ip dns mode https https://doh.example.com/dns-query
