What is an IP address?
Your IP address (Internet Protocol address) is the unique numerical label assigned to your device by your internet service provider whenever you go online. It is how every other computer on the internet knows where to send data when you request a webpage, stream a video, or send a message.
You can see your current public IP address — along with your ISP name, city, region, and country — instantly on the myipco.com homepage. No tools to install, no accounts needed.
The quick answer is that your IP address looks something like 203.0.113.47 (IPv4) or 2001:db8::1 (IPv6). But understanding what that number means, what it reveals about you, and the difference between your public and private IP is what most guides skip. This one does not.
Think of an IP address the way you think of a postal address. When you order a package, you give the sender your home address so the delivery driver knows where to bring it. An IP address works the same way: every data packet traveling across the internet carries a destination IP address, and the internet's routers use that address to deliver the packet to the right machine. Without it, there is no way to route anything anywhere.
Public IP vs private IP address — a common point of confusion
This is where most people get confused. You actually have two IP addresses active at any moment: a public IP address and a private IP address, and they serve completely different purposes.
Your public IP address is the one the outside world sees. It is assigned by your ISP and shared across your entire home or office network. When you visit a website, that website sees your public IP — not the address of your laptop or phone individually. You can see your current public IP on the myipco.com homepage.
Your private IP address is used only inside your local network. Your router assigns a private IP to every device that connects to it — your laptop might be 192.168.1.5, your phone 192.168.1.8, and your smart TV 192.168.1.12. These addresses are never visible to the outside internet; they exist purely for your router to route traffic to the right device at home.
The private IP ranges are standardized and reserved specifically for internal use: - 192.168.0.0 – 192.168.255.255 — the most common home network range - 10.0.0.0 – 10.255.255.255 — common in larger organizations - 172.16.0.0 – 172.31.255.255 — less common but valid private range
If you run a command like `ipconfig` (Windows), `ifconfig` (Mac), or `ip addr show` (Linux) and see an address starting with 192.168 or 10.x, that is your private IP. It is not useful for anything outside your local network. To know your public IP — the one that actually matters for privacy and troubleshooting — check myipco.com.

IPv4 vs IPv6 — why there are two versions
You may have noticed IP addresses come in two very different formats. IPv4 addresses look like four numbers separated by dots — 203.0.113.47 — while IPv6 addresses look like eight groups of hexadecimal characters separated by colons — 2001:0db8:85a3:0000:0000:8a2e:0370:7334.
The reason two versions coexist comes down to a supply problem. IPv4 can express roughly 4.3 billion unique addresses (2³²). That sounded like plenty in 1981 when the protocol was designed. It was not. By the early 2000s it was clear the internet would run out of IPv4 addresses, so IPv6 was developed to support 340 undecillion addresses (2¹²⁸ — a number so large it will never be exhausted).
Most modern devices and networks support both versions simultaneously, a setup called dual-stack. Your ISP may assign you both an IPv4 and an IPv6 address. The internet gradually transitions toward IPv6, but IPv4 remains widely used because most legacy infrastructure was built around it.
For a full explanation of how the two protocols differ and why it matters, see our detailed post on IPv4 vs IPv6.
What your IP address actually reveals about you
Your IP address is not anonymous — but it is also not as revealing as many people fear. Here is what it genuinely discloses, and what it does not:
What your IP does reveal:
- Your ISP — reliably and precisely. Anyone who looks up your IP can immediately see which internet service provider owns that address block. - Your approximate location — typically your city or region, but not your street address. IP geolocation databases map address ranges to geographic areas based on where ISPs have registered their infrastructure. Accuracy varies: in cities, it is usually accurate to within 20–50 miles. In rural areas, the database might place you in a different city entirely. For a deeper look at this, read our post on how accurate IP geolocation actually is. - Your organization or network — if you are on a corporate or university network, the IP may identify the institution. - Connection type hints — residential, business, data center, mobile carrier. These are increasingly tracked by fraud detection systems.
What your IP does not reveal:
- Your name, home address, or phone number - Your browsing history - The specific device you are using
Law enforcement can subpoena your ISP to connect your IP address to your identity, but a random website or person cannot do this on their own.
For a full breakdown of what someone can actually do with your IP address — and what the real risks are — see our post on what can someone do with your IP address.
Dynamic vs static IP addresses
Not all IP addresses are permanent. Most home internet connections use a dynamic IP address, which means your ISP assigns you an IP from a pool and may change it periodically — sometimes after every router restart, sometimes every few weeks, sometimes less often.
Dynamic IPs exist because IPv4 addresses are scarce and ISPs do not have enough to give every customer a permanent one. Instead, they maintain a shared pool and assign addresses as needed. When you are not connected, your IP can be reassigned to someone else.
A static IP address is one that never changes. Businesses typically use static IPs because they run servers — web servers, mail servers, VPNs — that need a consistent, predictable address so clients can always find them. Static IPs usually cost extra and must be requested from your ISP.
For most home users, dynamic IPs are not a problem. You can still do everything online with a dynamic IP. The main limitation is hosting a server at home — if your IP changes, people trying to connect to it by IP address will fail. Dynamic DNS (DDNS) services solve this by automatically updating a hostname whenever your IP changes.
One practical implication of dynamic IPs: if you see an "abuse" complaint tied to an IP address you currently hold, there is a real chance the previous holder of that IP was responsible.
How to find your IP address on any device
The fastest way to find your public IP address is to visit myipco.com — it shows your IP instantly along with geolocation details, ISP, and whether you are using a VPN or proxy.
If you need your private IP address (the address your router assigned to your device on the local network), here is how to find it by operating system:
Windows: Open Command Prompt and run `ipconfig`. Look for "IPv4 Address" under your active adapter. It will typically start with 192.168 or 10.
macOS: Go to System Settings → Network → select your connection → Details. The IP address shown is your private IP.
iPhone/iPad: Settings → Wi-Fi → tap the network name → your IP address is listed under "IPv4 Address."
Android: Settings → Network & Internet → Wi-Fi → tap the network name → scroll to see the IP address (exact path varies by manufacturer).
Linux: Run `ip addr show` in a terminal. Your private IP appears next to "inet" on your active interface (usually eth0 or wlan0).
Router admin panel: Log in to your router (usually at 192.168.1.1 or 192.168.0.1) to see both your private network configuration and your public IP as seen by your ISP.
How to hide or change your IP address
There are several legitimate reasons to want a different IP address: bypassing regional restrictions, improving privacy, preventing tracking, or troubleshooting network issues. The main methods are:
VPN (Virtual Private Network) — A VPN routes your traffic through a server in another location. Websites and services see the VPN server's IP address instead of yours. This is the most popular and practical method for most users. For a thorough explanation of how VPNs work, see our post on what a VPN is and how it works. For a step-by-step guide to actually hiding your IP, see how to hide your IP address.
Proxy server — A proxy acts as an intermediary between your device and the internet, forwarding your requests under a different IP. Proxies are generally faster than VPNs but offer no encryption. Read more in our guide on what a proxy server is.
Tor — Routes your traffic through multiple volunteer-operated relays, masking your IP with layers of encryption. Very strong privacy, but significantly slower than normal browsing.
Restarting your router — If your ISP assigns dynamic IPs, disconnecting and reconnecting will often give you a new IP. This is not guaranteed, but it works often enough to be worth trying.
Contacting your ISP — You can request a new IP directly from your ISP. For home users on dynamic plans, this is usually straightforward. For a complete walkthrough of all methods, see our post on how to change your IP address.
Whatever your reason for wanting a different IP, make sure you verify it actually changed afterward — the myipco.com homepage will show your current public IP immediately.
How to look up information about any IP address
You can use myipco.com not only to check your own IP but to look up details about any IP address — useful for investigating suspicious connections, diagnosing network issues, or verifying a server's location.
The myipco.com homepage will detect and display your IP automatically. For deeper network lookups — including DNS records, reverse DNS, and authoritative nameserver information — the DNS lookup tool is useful when troubleshooting connectivity or email delivery problems.
When you look up any IP address, here is the key information typically available:
- ASN (Autonomous System Number) — identifies the organization or network that controls the IP block. Every ISP, hosting provider, and large company has its own ASN. Learn more in our post on what an ASN is. - Geolocation — city, region, country, and approximate coordinates based on IP geolocation databases - Hostname (reverse DNS) — if the IP owner has configured a PTR record, you can resolve the IP back to a domain name - Proxy/VPN detection — whether the IP belongs to a known VPN provider, proxy, or Tor exit node
Understanding your IP address is the first step toward understanding your digital presence. Whether you are here to check what websites see when you connect, troubleshoot a network issue, or start thinking more seriously about your online privacy — you now have the foundation to go further.
