Question 1

What is a WHOIS lookup tool?

Accepted Answer

A WHOIS lookup tool retrieves public registration data for a domain name — including the registrar, registration date, expiry date, nameservers, and domain status — via the RDAP protocol.

Question 2

How do I check DNS records for a domain?

Accepted Answer

Use the DNS Lookup tool to instantly retrieve all DNS records for any domain: A (IP address), AAAA (IPv6), MX (mail servers), NS (nameservers), TXT (SPF/DKIM/verification), and CNAME records.

Question 3

How can I check if a domain's SSL certificate is valid?

Accepted Answer

The SSL/TLS Check tool reads the live certificate from any domain, showing the issuer, expiry date, days remaining, a security grade (A–F), and all Subject Alternative Names (SANs).

Question 4

How do I find when a domain expires?

Accepted Answer

The Check Expiry Date tool looks up the domain's expiration date via RDAP and shows the exact date, days remaining, and an urgency level — so you can act before it drops.

Question 5

How can I check if a domain name is available?

Accepted Answer

The TLD Availability tool checks whether a domain is registered or available using the RDAP protocol. It also checks 5 popular TLD alternatives (.com, .io, .ai, .co, .net) for the same name.

Question 6

Can I check multiple domain names at once?

Accepted Answer

Yes — the Bulk Availability tool checks up to 20 domains in parallel. Enter one domain per line and get availability status for all of them in seconds.

Question 7

How do I see a domain's history on the Wayback Machine?

Accepted Answer

The Wayback History tool queries the Internet Archive's CDX API to show when a domain was first captured, recent snapshots, and direct links to browse the full archive history.

Question 8

What is DNS propagation and how do I check it?

Accepted Answer

DNS propagation is the time it takes for updated DNS records to spread across global resolvers. The DNS Propagation tool checks your domain across 8 public DNS resolvers (Google, Cloudflare, Quad9 and more) simultaneously.

Question 9

How much is my domain worth?

Accepted Answer

The Domain Appraisal tool gives a free heuristic value estimate based on name length, TLD, word-likeness and domain age — returning a value range, not a fake precise number. It is not a substitute for a professional appraisal.

Question 10

What are HTTP security headers?

Accepted Answer

The Security Headers Checker inspects a domain's live HTTP response for six key security headers (CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy) and returns a letter grade.
