Whoisfreaks

@whoisfreaks check if 'mycompany-app.com', 'mycompany-app.io', and 'mycompany-app.dev' are available for registration

Bulk availability check complete for 3 domains: • mycompany-app.com — **Taken** (registered 2019-03-14, expires 2025-03-14) • mycompany-app.io — **Available** for registration • mycompany-app.dev — **Available** for registration Both .io and .dev TLDs are open. The .com variant is held by a domain parking service with privacy protection enabled. If you need alternative suggestions for the .com, I can run a separate availability check with recommendations.

This example shows the bulk domain availability tool handling multiple TLDs at once. Response times range from 16 seconds to 1 minute depending on registrar API latency. The tool returns registration status and expiration dates for taken domains, but does not provide transfer or purchase links—you'll need to complete registration through your preferred registrar.

@whoisfreaks run a bulk WHOIS lookup on the top 5 domains from our competitor analysis spreadsheet and summarize their registration patterns

WHOIS data retrieved for 5 competitor domains. Registration pattern summary: **Corporate registrations (3):** All use corporate privacy services (Domains By Proxy, WhoisGuard). Registered 2015–2018, consistently renewed through 2026. Name servers point to Cloudflare enterprise accounts. **Individual registrations (2):** One domain shows founder's personal email in historical records (now privacy-protected). Both registered 2020–2021, shorter renewal cycles (1-year vs. 3-year for corporate domains). All five domains share AWS Route 53 DNS infrastructure. No domains are flagged for transfer locks or disputes.

This example pairs the bulk WHOIS tool (max 100 domains per request) with AI synthesis to extract competitive intelligence. The tool returns raw registration data—contact info, name servers, status codes—which the AI then patterns into strategic insights. Note that privacy protection services often mask current contact details; historical WHOIS data requires a separate API call.

@whoisfreaks look up the ASN for IP 104.26.10.78 and tell me if it's part of a known CDN or hosting provider

ASN lookup for 104.26.10.78: **ASN:** AS13335 **Organization:** Cloudflare, Inc. **Network range:** 104.16.0.0/12 (1,048,576 IP addresses) **Type:** Content Delivery Network (CDN) This IP is part of Cloudflare's global Anycast network, used for DDoS protection, caching, and edge delivery. The ASN owns 2,500+ IPv4 prefixes across 310+ cities. If you're seeing traffic from this IP, it's likely proxied through Cloudflare—the origin server's real IP is masked. Use the DNS Live Lookup tool if you need to trace the domain's actual hosting provider behind the CDN.

This example demonstrates the ASN WHOIS tool's ability to identify network ownership and infrastructure context. Useful for security investigations, traffic analysis, or vendor due diligence. The tool provides network ranges and organization details but does not include real-time abuse reports or blocklist status—pair with IP Geolocation Lookup if you need security flags or geographic routing data.

When Whoisfreaks wins for incident response domain lookups

A 6-person security team investigating phishing campaigns needs to pivot from a suspicious domain to its registrant, hosting provider, and related infrastructure in under 60 seconds. Whoisfreaks is the right call here because the bulk WHOIS and ASN lookup tools let you query 20-30 domains in a single Switchy thread without switching contexts. The IP geolocation tool adds ISP and abuse contact data that speeds up takedown requests. The threshold: if your team runs more than 50 domain lookups per day, you'll hit API rate limits on the free tier and need to budget for paid access. If you're triaging fewer than 10 incidents per week, the MCP overhead isn't worth it—just use a browser tab. For teams in the middle, Whoisfreaks turns a 15-minute manual lookup into a 2-minute AI-assisted workflow.

When this MCP handles domain squatting checks at launch scale

A 3-person marketing team launching a rebrand needs to check if 80 domain variants are registered by squatters before filing trademarks. Whoisfreaks' bulk domain availability tool processes the entire list in under 2 minutes, returning registration status and suggesting alternatives for taken names. The WHOIS lookup adds registrant details so you can assess whether a domain is parked or actively used by a competitor. This works well for one-time audits or quarterly checks. The boundary: if you need real-time monitoring (daily scans for new registrations matching your brand), Whoisfreaks doesn't offer alerting—you'd need a dedicated brand protection service. For launch-phase due diligence or M&A domain audits, this MCP gives you the data without paying for enterprise monitoring you don't need yet.

When live DNS lookup beats your terminal for multi-region debugging

A 5-person platform team debugging a CDN failover issue needs to verify DNS propagation across 12 subdomains and 4 geographic regions in real time. Whoisfreaks' DNS live lookup tool runs queries from multiple vantage points and surfaces TTL mismatches or stale records that explain why traffic isn't routing correctly. The bulk DNS lookup handles the full subdomain list in one request, which is faster than running dig commands in a loop. The trade-off: if your DNS stack is already instrumented with observability tooling (Datadog, Grafana), you probably don't need this MCP—your dashboards show the same data. This wins when you're troubleshooting a one-off incident or onboarding a junior engineer who doesn't have dig muscle memory yet. For ad-hoc DNS debugging in Switchy, it's faster than context-switching to a terminal.
