Details
User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:62.0) Gecko/20100101 Firefox/62.0
Steps to reproduce:
1. Add DNS A record for an intranet site in the private IP range (i.e. in 172.16.0.0/16);
2. Use a DNS query tool to make sure the record is propagated to CloudFlare;
3. Enable DNS-over-HTTPS in FireFox:
- network.trr.bootstrapAddress = 1.1.1.1
- network.trr.mode = 3
- network.trr.uri = https://cloudflare-dns.com/dns-query
4. Try to visit the said intranet (HTTPS) site.
Actual results:
Firefox fails to load the site.
Expected results:
Firefox succeeds in loading the site.

More concretely, I have an intranet site at 172.16.1.48. Firefox has no trouble loading that site when network.trr.mode is set to 0.

Never mind. I just realized that there's a network.trr.allow-rfc1918 option. It would be nice if FF's failure page provided some explanation.
