DNS server and dns routing?

[sgon00]

I am very confused about how to do dns routing when use v2ray as a dns server. Will dns server use dns object?

Please check the following partial config:

"dns": {
  "servers": [
      "1.1.1.1",
      {
        "address": "114.114.114.114",
        "port": 53,
        "domains": ["geosite:cn"]
      },
      "localhost"
  ]
},

......

"inbounds": [
{
  "port": 53,
  "tag": "dns-in",
  "protocol": "dokodemo-door",
  "settings": {
    "address": "1.1.1.1",
    "port": 53,
    "network": "tcp,udp"
  }
}
],

......

"outbounds": [
{
  "protocol": "dns",
  "tag": "dns-out"
}
],

......

"routing": {
  "rules": [
  {
    "type": "field",
    "inboundTag": ["dns-in"],
    "outboundTag": "dns-out"
  }
  ]

......

You can see this config, when I use v2ray as a DNS server (port 53, dokodemo-door, dns-in tag), it seems it always use 1.1.1.1 to resolve domains.
Can the "dns" object take any effects here?
If not, how can I make chinese domains use 114.114.114.114 and other domains use 1.1.1.1 when I use v2ray as dns server? Is that possible?

The DNS server and "dns" object is very confusing to me.

Because I am using v2ray in linux router with iptables rules, I am trying to figure out how to do dns routing based on domain names. For socks protocol, it's very easy. But for router setup, it's very confused.

Thanks a lot.

I think I can answer my own question now.

By testing and reading v2ray dns protocol doc and v2ray dns object doc, I can confirm that dns server does use dns object.

This is because the outbound protocol dns will use dns object to resolve (A and AAAA) records.
