What's My IP Address?

🔍 DNS Lookup — How to Use

🔍 Read the full Dns Lookup guide →

The DNS Lookup tool lets you examine the DNS records of any domain. DNS (Domain Name System) translates human-readable domain names like example.com into IP addresses that computers use to communicate.

How to use: Enter any domain name (e.g., google.com) and click Lookup. The tool resolves all common record types — A (IPv4 address), AAAA (IPv6 address), MX (mail servers), TXT (text records like SPF/DKIM), NS (name servers), and CNAME (canonical names).

What the results mean: A-records show where a website is hosted. MX records reveal the email provider. TXT records often contain security policies (SPF, DKIM, DMARC) that help prevent email spoofing. If no records are found, the domain may not exist or DNS propagation may be incomplete.

Use cases: Troubleshooting website connectivity, verifying DNS changes after migration, checking email server configuration, or investigating domain ownership from a security perspective.

📋 WHOIS Lookup — How to Use

The WHOIS Lookup tool retrieves domain registration information from public WHOIS databases. Every registered domain has WHOIS records that show who owns it, when it was registered, and when it expires.

How to use: Enter a domain name and click Lookup. The tool queries multiple WHOIS sources and returns the domain's registration details including the registrar name, creation and expiration dates, and name server information.

What the results mean: The creation date tells you how old a domain is — older domains often have more authority in search rankings. The expiration date shows when the registration needs renewal. The name servers reveal which hosting provider or DNS service the domain uses. Some WHOIS records may show registrant contact information (often hidden by privacy protection).

Use cases: Verifying domain ownership before purchase, checking when a domain was registered (useful for SEO research), identifying domain squatters, or investigating suspicious websites.

🌍 IP Lookup — How to Use

🌍 Read the full Ip Geolocation guide →

The IP Lookup tool provides geolocation and network information for any IP address. It reveals the approximate geographic location, ISP, and organization associated with the IP.

How to use: Enter any IP address (e.g., 8.8.8.8) and click Lookup. The tool returns location data including country, region, city, and coordinates, plus ISP and ASN (Autonomous System Number) information.

What the results mean: The location is approximate — IP geolocation can pinpoint a city but rarely an exact address. The ISP reveals which company provides internet service for that IP. The ASN identifies the network block owner. Reverse DNS (PTR record) shows the hostname associated with the IP, which is useful for identifying mail servers or hosting providers.

Use cases: Identifying the origin of website traffic, checking if a VPN is being used, troubleshooting network routing issues, or verifying that your own IP's location data is accurate.

📨 HTTP Headers — How to Use

📨 Read the full Http Headers guide →

The HTTP Headers tool shows the headers your browser sends with every request, plus the headers the server responds with. HTTP headers contain metadata about the request and response.

How to use: No input needed — the tool automatically captures and displays your request headers when you open the panel. It shows both request headers (sent by your browser) and response headers (returned by the IPChecks server).

What the results mean: Request headers reveal your browser type (User-Agent), accepted languages (Accept-Language), caching preferences (Cache-Control), and connection details (Connection). Response headers show the server software, content type, caching policies, and security headers like Content-Security-Policy and X-Frame-Options that protect against attacks.

Use cases: Debugging website issues (caching, redirects), verifying security headers are properly configured, understanding what data your browser shares with websites, or checking if your browser's privacy settings are working.

🕵️ WebRTC Leak Test — How to Use

The WebRTC Leak Test checks if your real IP address is exposed through WebRTC (Web Real-Time Communication), a browser technology used for video calls and peer-to-peer connections. VPN users often don't realize that WebRTC can bypass the VPN tunnel and reveal their actual IP.

How to use: Click "Test WebRTC Leak". The tool creates a test WebRTC connection and captures all local IP addresses your browser exposes. If the exposed IPs include an address that doesn't match your VPN's IP, there's a leak.

What the results mean: A clean test shows only your VPN/proxy IP (or your regular public IP if not using a VPN). A failed test shows additional IPs, typically your local network IP (like 192.168.x.x) or your ISP-assigned IP — these are leaks. Not all browsers support WebRTC blocking to the same degree.

How to fix leaks: Use browser extensions like uBlock Origin or WebRTC Leak Prevent, disable WebRTC in browser settings (if supported), or use a VPN that includes WebRTC leak protection.

🚫 Blacklist Check — How to Use

🚫 Read the full Blacklist Check guide →

The Blacklist Check tool scans your IP address against multiple DNS-based blacklists (DNSBLs). These databases track IP addresses known for sending spam, hosting malware, or engaging in malicious activity.

How to use: Click "Check My IP". The tool checks your current public IP against major blacklists including Spamhaus (zen.spamhaus.org), Barracuda (b.barracudacentral.org), SpamCop (bl.spamcop.net), and AbuseAT (dnsbl-1.uceprotect.net), among others.

What the results mean: A green listing means your IP is clean on that blacklist. A red listing means your IP appears on that blacklist — this can cause email delivery issues (your emails may be rejected by recipients) or website trust problems. You'll also see the type of listing (e.g., "spam source", "open relay").

What to do if listed: Most blacklists provide delisting instructions on their websites. Common causes: compromised server sending spam, infected device on your network, or shared hosting IP used by a spammer. Fix the root cause first, then request delisting.
