Toolkit
All tools
Focused, fast utilities for diagnosing IP, network and browser behaviour. Every tool runs without an account and without storing your data.
IP Tools
Find and inspect the public IP address you are connecting from.
- Popular IP
What is my IP
See your public IP address, location, ISP and ASN instantly.
- IP
IPv4 Checker
Check your IPv4 address and confirm whether IPv4 connectivity works.
- IP
IPv6 Checker
Test whether your connection supports IPv6 and see your IPv6 address.
- Popular IP
IP Lookup
Look up geolocation, ISP and ASN details for any public IP address.
- IP
Network Dashboard
Every network and browser fact about this connection, on one page.
- IP
My IP History
A private, local record of how your connection has changed over time.
Network Tools
Query the public infrastructure behind a domain or host.
- Popular Network
Internet Speed Test
Measure your download speed, upload speed, latency and jitter.
- Popular Network
DNS Checker
Look up A, AAAA, CNAME, MX, TXT, NS, SOA and CAA records for any domain.
- Network
DNS Propagation Checker
Compare DNS results across multiple public resolvers to see if a change has spread.
- Network
Port Checker
Check whether a TCP port is open and reachable on a public host.
- Network
Reverse DNS Lookup
Find the PTR host name an IPv4 or IPv6 address resolves back to.
- Network
WHOIS Lookup
Look up registrar, creation and expiry dates and nameservers for a domain.
Security Tools
Inspect the TLS certificates and security headers a site actually serves.
- Popular Security
VPN & Proxy Detection
Check whether your connection looks like a VPN, proxy, Tor exit or datacenter.
- Popular Security
SSL Certificate Checker
Inspect a site’s TLS certificate, expiry date, issuer and SANs.
- Security
HTTP Headers Checker
See the response headers, redirects and security headers a URL returns.
- Popular Security
Email DNS Checker
Check the MX, SPF, DKIM and DMARC records that decide whether your domain can send and receive mail.
Developer Tools
Offline calculators and reference lookups that need no network access.
- Developer
Subnet Calculator
Calculate network, broadcast, usable range and masks for IPv4 and IPv6 CIDR.
- Developer
MAC Address Lookup
Identify the vendor behind a MAC address and decode its OUI flags.
- Developer
Redirect Checker
Follow a URL through every redirect and see the status codes, the final destination and any insecure hop.
Browser Tools
See exactly what your browser reveals to every site you visit.
- Browser
User-Agent Checker
See your raw User-Agent string and what it says about your setup.
- Browser
Browser Info
A full report of what your browser exposes to every website.
- Browser
Screen Resolution
Check your screen resolution, viewport size and pixel ratio.
- Browser
Timezone Checker
See your detected timezone, UTC offset and local time.
Guides
Background reading for the results these tools return — what the fields mean, and which one answers which question.
- Public vs private IP addresses Why can I look up 8.8.8.8 but not 192.168.1.1? What separates a globally routable address from one that only exists inside your network, and why lookup tools refuse the second kind.
- DNS record types explained What do A, AAAA, CNAME, MX, TXT, NS, SOA and CAA actually do? A practical reference for the eight record types a domain normally publishes, and which one to check for a given problem.
- HTTP security headers explained Which response headers matter, and what does each one prevent? What HSTS, CSP, X-Frame-Options and the rest defend against, and which are worth setting on an ordinary site.
- How to read an SSL certificate What do the issuer, chain, SANs and expiry date on a certificate mean? How to interpret the fields a certificate check returns, and what actually makes a certificate untrusted.
- How to find your IP address Where do I actually find my IP address, and which one do I need? The difference between the address the internet sees and the one your router handed you, and how to find each on any device.
- IPv4 vs IPv6 What is the difference, and does it matter that I have one and not the other? Why two address systems exist, what changed between them, and how to tell whether your connection actually supports both.
- VPN vs proxy They both change my IP address — so what is the actual difference? What each one carries, what each one encrypts, who can see what, and which problems each actually solves.
- How a speed test works Why is my speed test result different from what I pay for? What download, upload, latency and jitter are actually measuring, and the reasons a result can be lower than your plan.
- How to check if a port is open The checker says filtered — what does that mean and what do I change? What open, closed and filtered actually tell you, why testing from your own machine answers a different question, and how to work back to the cause.
- DNS troubleshooting The site works for me and not for them — how do I find out why? A method for narrowing a DNS problem down: propagation, caching, TTL, and the checks that separate a records problem from a delegation problem.
- HTTP status codes explained What is the server actually telling me with 301, 403, 502 and the rest? The codes that matter in practice, what each one says about who has the problem, and the pairs that are routinely confused for one another.
How to pick the right tool
Most network questions fall into one of four shapes, and the tool you want follows from which one you are actually asking.
- "What does the internet see when I connect?" — start at what is my IP, then IP Lookup for the network behind an address and Speed Test for throughput.
- "Where does this domain point?" — DNS Checker reads the records, DNS Propagation compares public resolvers after a change, and WHOIS shows who registered it and when it expires.
- "Is this host reachable and correctly configured?" — Port Checker for TCP reachability, SSL Checker for the certificate, and HTTP Headers for redirects and security headers.
- "I am working out addressing." — Subnet Calculator for CIDR maths, Reverse DNS for the name behind an address, and MAC Lookup for the hardware vendor.
Where each result comes from
The distinction matters when you are debugging. Some tools describe your browser, some describe your connection, and some run from IPGet's server — which is a different vantage point from yours.
- From IPGet's server: DNS Checker, DNS Propagation, Reverse DNS, WHOIS, Port Checker, SSL Checker and HTTP Headers. These answer "what does the public internet see", not "what does my machine see" — which is exactly why they can confirm a firewall rule or a DNS change that looks fine locally.
- From your browser: User-Agent, Browser Info, Screen Resolution and Timezone. Nothing is sent anywhere to produce them.
- Entirely offline: Subnet Calculator and MAC Lookup need no network at all — the maths and the vendor database both run without a request leaving the page.
Every tool is free, needs no account, and stores nothing about the lookups you run. See the privacy policy for exactly what that means.
