DNS

V2Ray دارای یک سرور DNS داخلی است که رله DNS را برای اجزای دیگر فراهم می کند.

پرسش های DNS که توسط این سرویس DNS رله می شود نیز براساس تنظیمات مسیریابی ارسال می شود. هیچ پیکربندی اضافی لازم نیست.

DnsObject

DnsObject به عنوان dns فیلد در پیکربندی سطح بالا استفاده می شود.

{
  "hosts": {
    "baidu.com": "127.0.0.1"
  },
  "servers": [
    {
      "address": "1.2.3.4",
      "port": 5353,
      "domains": [
        "domain:v2ray.com"
      ]
    },
    "8.8.8.8",
    "8.8.4.4",
    "localhost"
  ],
  "clientIp": "1.2.3.4",
  "tag": "dns_inbound"
}

hosts: map{string: address}

A list of static addresses, in the form of domain:address. Each entry has a domain name as key and IP or domain address as value. If a DNS query targets one of the domains in this list, the corresponding IP will be returned immediately and DNS query will not be relayed, or the corresponding domain address will be used for further DNS queries, instead of the previous one.

The format of domains is:

• Plaintext: When the targeting domain is exactly the value, the rule takes effect. Example: rule "v2ray.com" matches "v2ray.com", but not "www.v2ray.com".
• Regular expression: Begining with "regexp:", the rest is a regular expression. When the regexp matches targeting domain, this rule takes effect. Example: rule "regexp:\\.goo.*\\.com$" matches "www.google.com" and "fonts.googleapis.com", but not "google.com".
• Subdomain (recommended): Begining with "domain:" and the rest is a domain. When the targeting domain is exactly the value, or is a subdomain of the value, this rule takes effect. Example: rule "domain:v2ray.com" matches "www.v2ray.com", "v2ray.com", but not "xv2ray.com".
• Keyword: Begining with "keyword:" and the rest is a pattern. If this string matches any part of the targeting domain, this rule takes effet. Example: rule "keyword:sina.com" matches targeting domain "sina.com", "sina.com.cn" and "www.sina.com", but not "sina.cn".
• Pre-defined domain list: Begining with "geosite:" and the rest is a name, such as geosite:google or geosite:cn. See Pre-defined domain list for more detail.

سرور: \ [رشته | ServerObject | "localhost" ]

فهرست سرورهای DNS. هر سرور ممکن است در سه فرمت مشخص شود: آدرس IP، ServerObjectیا "localhost".

هنگامی که یک سرور یک آدرس IP است، مانند "8.8.8.8"، V2Ray در DNS UDP روی 53 آدرس در این آدرس نمایش داده می شود.

هنگامی که یک سرور "localhost"، V2Ray میزبان محلی DNS را نمایش می دهد.

clientIp: string

آدرس آی پی دستگاه فعلی. اگر مشخص شود، V2Ray از این IP به عنوان EDNS-Client-Subnet استفاده می کند. این IP نمی تواند یک آدرس خصوصی باشد.

tag: string

(V2Ray 4.13+) All traffic initiated from this DNS, except to localhost, will have this tag as inbound. It can be used for routing.

ServerObject

{
  "address": "1.2.3.4",
  "port": 5353,
  "domains": [
    "domain:v2ray.com"
  ],
}

address: address

Address of the DNS server. For now only UDP servers are supported.

port: number

Port of the DNS server. Usually it is 53 or 5353.

domains: [string]

A list of domains. If the domain of enquire matches one of the list, this DNS server will be prioritized for DNS query for this domain.

Domain name format is the same as in routing.

When a DNS server has the domain in its domain list, the domain will be queried in this server first, and then other servers. Otherwise DNS queries are sent to DNS servers in the order they appear in the config file.
