dnsx DNS 批量解析方法论

dnsx 是 ProjectDiscovery 出品的高速 DNS 工具。核心优势：多记录类型 + 通配符自动过滤 + 管道友好。

项目地址：https://github.com/projectdiscovery/dnsx

Phase 1: 基本解析

# 单域名 A 记录
echo target.com | dnsx -a -resp

# 批量解析
dnsx -l subdomains.txt -a -resp -silent

# 多记录类型
echo target.com | dnsx -a -aaaa -cname -ns -mx -txt -resp

Phase 2: 子域名验证

# 验证子域名存活
subfinder -d target.com -silent | dnsx -silent

# 过滤通配符域名
subfinder -d target.com -silent | dnsx -wd target.com -silent

# 提取 IP 地址
subfinder -d target.com -silent | dnsx -a -resp-only -silent | sort -u

Phase 3: 高级用法

# 暴力枚举子域名
dnsx -d target.com -w subdomains-wordlist.txt -silent

# 自定义 DNS 解析器
dnsx -l domains.txt -a -resp -r 8.8.8.8,1.1.1.1

# PTR 反向解析
echo 10.0.0.1 | dnsx -ptr -resp

# JSON 输出
dnsx -l domains.txt -a -resp -json -o results.json

# 控制并发
dnsx -l domains.txt -a -t 200 -silent

管道集成

# 子域名 → DNS 解析 → IP 去重
subfinder -d target.com -silent | dnsx -a -resp-only -silent | sort -u

# 子域名 → DNS 验证 → HTTP 探活
subfinder -d target.com -silent | dnsx -silent | httpx -silent

# CNAME 提取（用于子域名接管检测）
subfinder -d target.com -silent | dnsx -cname -resp -silent
