PacketWizard helps network engineers, system administrators, and security teams diagnose DNS, IP, TLS, connectivity, and mail authentication issues — without installing another desktop utility.
Privacy note: these details are computed for your current request only. PacketWizard does not store your IP address for this lookup.
Measure download and upload throughput, latency, jitter, and HTTP reliability with an IT-focused connection quality report.
Look up DNS and WHOIS, inspect TLS and HTTP, check ports, and measure connection quality — then jump to the next related diagnostic.
See the public IPv4 or IPv6 address internet services observe for your current browser session.
Measure download and upload throughput, latency, jitter, and HTTP reliability with an IT-focused connection quality report.
Query DNS records for a hostname or domain.
Look up domain registration details using RDAP with registrar, status, and nameserver information.
Investigate any IP address: ownership, ASN, RDAP allocation, reverse DNS, approximate geolocation, and proxy/VPN signals.
Inspect TLS handshakes, cipher suites, and certificate chains.
Analyze HTTP behavior, redirects, security headers, cookies, compression, and caching.
Test TCP port reachability against a target host.
Perform PTR lookups for IP addresses.
SPF, DKIM, DMARC, BIMI, and MTA-STS inspectors for mail authentication and deliverability.
PacketWizard is for IT professionals, network engineers, system administrators, and security teams — not a generic consumer gadget site.
DNS, IP intelligence, WHOIS/RDAP, TLS, ports, and speed tests in one place — the daily stack for network engineers.
Structured output, copy-ready values, and investigation-friendly layouts designed for tickets, change windows, and on-call.
Quick ownership, certificate, and mail-auth checks when you need to validate infrastructure during an investigation.
Tools prioritize consistent results. The internet speed test is intentionally simple so it finishes when you need it.
Public IP lookup is computed per request and not stored. Many utilities run entirely in your browser.
Clear tool pages, internal links, and search-friendly docs so the right diagnostic is one query away.
A preview of upcoming status monitoring for the platforms your organization depends on. Live health signals arrive in a future release.

Short, accurate answers to the questions behind every network lookup.
A public IP address is the unique, internet-routable address your network presents to the outside world. Websites and services use it to send responses back to you. Everyone behind the same router or gateway typically shares one public IP.
IPv4 is the fourth version of the Internet Protocol and the most widely deployed. It uses 32-bit addresses written as four numbers (for example, 203.0.113.42), which allows for roughly 4.3 billion unique addresses.
IPv6 is the successor to IPv4, created to solve address exhaustion. It uses 128-bit addresses written in hexadecimal (for example, 2001:db8::1), providing an effectively unlimited pool of addresses and simpler routing.
Approximate location comes from geolocation databases that map IP ranges to regions based on how providers allocate and announce them. It reflects your ISP's network, not GPS, so it is an estimate — usually accurate to a city or region.
Yes. A VPN routes your traffic through a remote server, so services see that server's IP and location instead of your own. This masks your real public IP and can make you appear to connect from a different city or country.
Common questions about PacketWizard, public IPs, and mail authentication tools.
PacketWizard is a browser-based networking and infrastructure toolkit for IT professionals, network engineers, system administrators, and security teams. It covers IP lookups, DNS, TLS, mail authentication, identity, and everyday utilities in one workspace.
Your IP address is the unique identifier your network uses on the internet. PacketWizard shows your public IP — the address websites and services see when your browser connects — via the What Is My IP tool and on the homepage when available.
Most home and mobile connections use dynamic IP addresses that your provider reassigns periodically or when your router reconnects. Switching networks, restarting equipment, or connecting through a VPN will also change the public IP you present.
IPv4 uses 32-bit addresses (like 203.0.113.42) and supports about 4.3 billion addresses. IPv6 uses 128-bit addresses (like 2001:db8::1) for a vastly larger pool. Many networks now run both, so you may have an IPv4 and an IPv6 address at the same time.
Yes. The Mail Authentication category includes SPF, DKIM, and DMARC inspectors and builders, plus BIMI, MTA-STS, TLS-RPT, and an email header analyzer for delivery timelines.
Public IP lookup is computed for your current request only and is not saved as history. Client-side utilities run in your browser. Avoid pasting secrets into shared recordings or tickets.
IP geolocation is an approximation based on how providers allocate address ranges. It is usually accurate to a city or region but can be off, especially for mobile networks, VPNs, or business connections. It is not GPS-precise.
