DNS over HTTPs issue

more options

The FF set to a value of network.trr.mode=3, network.trr.bootstrapaddress=8.8.8.8 and netork.trr.uri=https://dns.google/dns-query I can resolution but if I change the dns resolver network.trr.bootstrapaddress=9.9.9.9 another DNS resolver it does not work.

Am I correct in thinking that the bootstrapaddress is to point to any DNS server capable of resolving the DOH domain? Because I found it only resolves for it own DOH.

Chosen solution

network.trr.bootstrapaddress is the IP address of host of network.trr.uri.

E.g., if you use https://dns.google/dns-query,

$ nslookup dns.google Non-authoritative answer: Name: dns.google Address: 8.8.4.4 Name: dns.google Address: 8.8.8.8

you can set the network.trr.bootstrapaddress to 8.8.8.8 or 8.8.4.4

If you use https://jp.tiar.app/dns-query,

$ nslookup jp.tiar.app Non-authoritative answer: Name: jp.tiar.app Address: 172.104.93.80

you must set the network.trr.bootstrapaddress to 172.104.93.80
