Use this skill when you need to look up DNS records, perform reverse DNS, check WHOIS data, or verify nameservers. Zero auth required.

当你需要查询DNS记录、执行反向DNS、检查WHOIS数据或者验证域名服务器时使用本技能，无需任何身份验证。

Tool	What it does
`dns_lookup`	Look up A, AAAA, MX, TXT, NS, CNAME, SOA, SRV, or PTR records
`reverse_dns`	Reverse DNS (PTR) lookup on an IP address
`resolve_all`	Resolve A, AAAA, MX, TXT, NS, CNAME in one call
`check_nameservers`	Get nameserver (NS) records for a domain
`whois`	Query WHOIS data (follows IANA referrals to registrar)

工具	功能说明
`dns_lookup`	查询A、AAAA、MX、TXT、NS、CNAME、SOA、SRV或PTR记录
`reverse_dns`	对IP地址执行反向DNS（PTR）查询
`resolve_all`	单次调用即可解析A、AAAA、MX、TXT、NS、CNAME记录
`check_nameservers`	获取域名的域名服务器（NS）记录
`whois`	查询WHOIS数据（遵循IANA跳转规则获取注册商数据）

For general domain investigation: start with
```
resolve_all
```
to see everything at once
For specific record types: use
```
dns_lookup
```
with the
```
type
```
parameter
For IP investigation: use
```
reverse_dns
```
to find the hostname
For domain ownership: use
```
whois
```

```
dns_lookup
```
with
```
type: "MX"
```
is the go-to for email delivery debugging
```
resolve_all
```
returns all common record types in one call — most efficient for initial investigation
```
whois
```
follows IANA referrals automatically, so it works for any TLD
No API keys or auth needed — uses Node.js built-in DNS and public WHOIS servers
