# dns-lookup

DNS record lookups (A, AAAA, MX, TXT, CNAME, NS, SOA), reverse DNS (PTR), WHOIS/RDAP domain info, and IP geolocation.

## Data Handling

This skill sends domain names and IP addresses to an external API. The service does not store or log input data beyond the immediate response.

## Endpoints

```bash
curl -X POST https://dns.agentutil.net/v1/lookup \
  -H "Content-Type: application/json" \

```

Types: A, AAAA, MX, TXT, CNAME, NS, SOA, ANY. Default: A.

### Reverse DNS

```bash
curl -X POST https://dns.agentutil.net/v1/reverse \
  -H "Content-Type: application/json" \
  -d '{"ip": "8.8.8.8"}'
```

### WHOIS

```bash
curl -X POST https://dns.agentutil.net/v1/whois \
  -H "Content-Type: application/json" \
  -d '{"domain": "example.com"}'
```

### IP Geolocation

```bash
curl -X POST https://dns.agentutil.net/v1/geoip \
  -H "Content-Type: application/json" \
  -d '{"ip": "8.8.8.8"}'
```

## Response Format

{
  "records": [{"type": "A", "value": "93.184.216.34", "ttl": 300}],
