What Is an IP Address?
If you're new to networking, think of an IP address as a mailing address — but for your device on the internet.
Think of an IP address as a mailing address for your device. Just like the postal service needs a street address to deliver a letter, the internet needs an IP address to deliver the webpage you requested back to your computer, phone, or tablet.
Without an IP address, the internet wouldn't know where to send data. Every time you load a page, stream a video, or send a message, your device's IP address tells the remote server exactly where to send the response.
The IP address shown above is your public IP — the one the rest of the internet sees. It's assigned by your Internet Service Provider (ISP) and is shared by all devices on your home network.
Address Analogy
How Your Connection Works
Every time you visit a website, your request passes through multiple network layers. Here's the path your data takes from your device to the server and back.

Public vs Private IP
Your home network has two types of IP addresses, and understanding the difference helps explain why this page shows an IP that doesn't match your device settings.
A private IP address is like a room number inside a building — it only makes sense inside your local network. Your router assigns these addresses (like 192.168.1.5) to each device: your laptop, phone, smart TV, and so on.
A public IP address is like the building's street address — it's how the outside world finds you. Your entire household shares a single public IP assigned by your ISP.
Your router uses a process called NAT (Network Address Translation) to bridge the gap. It translates between private and public addresses so all your devices can share one public IP when communicating with the internet.
Private IP Ranges
| Range | Addresses | Typical Use |
|---|---|---|
10.0.0.0/8 |
16.7 million | Large / corporate networks |
172.16.0.0/12 |
1 million | Medium networks |
192.168.0.0/16 |
65,536 | Home networks (most common) |
Static vs Dynamic IP
Not all IP addresses behave the same way. Whether your IP stays the same or changes periodically depends on how your ISP assigns it.
Fixed
- Assigned by ISP (manual)
- Changes Never
- Used by Servers, businesses
- Cost Extra fee
DHCP
- Assigned by ISP (DHCP)
- Changes Periodically
- Used by Home users
- Cost Included
Most home internet connections use dynamic IP. Your ISP assigns a new address from a pool each time your router reconnects. If you need a permanent address (for hosting a server, for example), ask your ISP about a static IP add-on.
Inside an IP Packet
Every piece of data that crosses the internet is wrapped in an IP packet. Understanding its structure helps explain what an IP lookup actually reads.
Think of an IP packet as a postal envelope. The header is the addressing label — it tells routers where the packet came from and where it's going. The payload is the actual content inside, such as part of a web page, an image, or a video stream.
An IPv4 header is typically 20 bytes long (up to 60 with options). It contains everything routers need to forward the packet: source and destination addresses, a time-to-live counter that prevents infinite loops, a protocol field that tells the receiving host whether the payload is TCP, UDP, or something else, and a checksum to catch transmission errors.
When you run an IP lookup, you're reading metadata associated with the Source IP and Destination IP fields — the two 32-bit addresses in the header that identify sender and receiver. Geolocation databases map these addresses to physical locations, ISPs, and autonomous systems.
IPv4 Header Fields
| Field | Size | Description |
|---|---|---|
Version |
4 bits | IP version (4 for IPv4) |
IHL |
4 bits | Header length in 32-bit words |
Type of Service |
8 bits | Priority and QoS flags |
Total Length |
16 bits | Entire packet size in bytes |
Identification |
16 bits | Fragment identification |
Flags |
3 bits | Fragmentation control |
Fragment Offset |
13 bits | Position within fragmented packet |
TTL |
8 bits | Max hops before packet is discarded |
Protocol |
8 bits | Upper-layer protocol (TCP=6, UDP=17) |
Header Checksum |
16 bits | Error-checking for the header |
Source IP |
32 bits | Sender's IP address |
Destination IP |
32 bits | Receiver's IP address |
When you run an IP lookup, you're essentially looking up the metadata associated with the Source IP field — the address that identifies where a packet came from.
IPv4 vs IPv6
The internet is transitioning from IPv4 to IPv6 to accommodate the growing number of connected devices. Here's how the two protocols compare.

- Address size 32-bit
- Total addresses ~4.3 billion
- Format Dotted decimal
- Header size 20-60 bytes
- NAT Required
- Traffic share

- Total addresses ~340 undecillion
- Format Hex colon notation
- Header size 40 bytes (fixed)
- NAT Not needed

Does a VPN Change My IP?
A VPN encrypts your traffic and routes it through a server in another location. Websites see the VPN server's IP address instead of yours — here's how that works.

This page shows the IP as seen by our server. If you're using a VPN, it shows the VPN's exit IP — not your real one.
Does a VPN Make You Secure?
YouTube ads make VPNs sound like a magic shield against hackers, governments, and identity theft. They aren't. A VPN is a useful privacy tool for specific situations, but most of what sponsored videos claim is marketing — here's what a VPN actually does and doesn't do.
“A VPN makes you anonymous”
Reality: You shift trust from your ISP to the VPN provider. The VPN sees every site you visit. Many “no-log” VPNs have been subpoenaed and handed over data; some have been caught logging despite their marketing. Cookies, browser fingerprints, and account logins identify you regardless of IP.
“A VPN protects you from hackers”
Reality: The real protection against eavesdropping on public Wi-Fi is HTTPS/TLS, which encrypts your connection end-to-end to the actual site. Over 95% of the web is HTTPS today. A VPN was more useful when plain HTTP was common — now it’s mostly a tunnel inside an already-encrypted connection.
“A VPN stops tracking and ads”
Reality: Cookies, browser fingerprinting, account logins (Google, Facebook, Amazon), and third-party tracker networks all work regardless of your IP. Changing your IP doesn’t stop a site from recognising you once you log in.
“A VPN protects you from malware and phishing”
Reality: A VPN only routes traffic — it does not inspect what’s inside. Malware, phishing links, and scam sites reach you the same way with or without a VPN. Endpoint security (browser, antivirus, DNS filtering) is what actually helps.
“A VPN hides you from the government”
Reality: Not from serious adversaries. Traffic correlation, endpoint compromise, legal requests to the VPN provider, and metadata from payment methods and accounts all bypass the VPN. Many VPN companies operate in jurisdictions that cooperate with law enforcement requests.
“A VPN encrypts everything”
Reality: Only the tunnel between your device and the VPN server is encrypted by the VPN. After the exit server, your traffic is as encrypted — or not — as it would be without a VPN. Plain HTTP stays plain; HTTPS was already encrypted anyway.
When a VPN genuinely helps: hiding which sites you visit from your ISP or local network admin, accessing geo-restricted content, reaching your employer’s internal network remotely, and privacy on a truly untrusted network. A better mental model: a VPN moves the “who sees my traffic metadata” problem from your ISP to the VPN company. That can be an upgrade if you picked a reputable paid provider in a jurisdiction you trust — but it’s a lateral move, not a force field.
Common Uses for IP Lookup
IP address lookup is used across security, operations, compliance, and troubleshooting.
Security Analysis
Identify the origin of suspicious traffic, brute-force attempts, or DDoS attacks. IP geolocation and ASN data reveal whether traffic comes from known malicious networks.
Geolocation Verification
Verify that your VPN or proxy is routing traffic through the expected region. Confirm geo-restricted content is served correctly based on apparent location.
Network Troubleshooting
Determine your public-facing IP when debugging connectivity, configuring firewalls, or setting up remote access after an ISP assigns a new address.
Compliance & Access Control
Enforce geographic access policies for GDPR and data residency. Validate API requests originate from authorized networks.
Frequently Asked Questions
Quick answers to the most common questions about IP addresses.
No. An IP address only reveals an approximate location — typically a city or region, never a street address. Geolocation databases map IPs to the ISP's infrastructure, not to individual homes. Law enforcement can request exact data from your ISP with a court order, but a random person on the internet cannot pinpoint where you live from your IP alone.
Yes, there are several ways. The simplest is to restart your router — if you have a dynamic IP, your ISP will often assign a new one. For instant changes, use a VPN or proxy service, which masks your real IP with the server's address. You can also contact your ISP to request a different IP or a static IP assignment.
It depends. Most home connections use a dynamic IP, which can change when your router restarts or your ISP's lease expires. Business connections and servers often use a static IP that never changes. If you need a permanent address, ask your ISP about a static IP option.
By itself, an IP address is not dangerous — every website you visit can see it. However, it can be used to estimate your general location or target your connection with unwanted traffic. To stay safe, keep your router firmware updated, use a firewall, and consider a reputable VPN if you want to hide your IP and browsing metadata from your ISP — but see the section above on what a VPN does and doesn’t actually protect.
An IPv4 address like 192.168.1.10 has four numbers called octets, separated by dots. Each octet ranges from 0 to 255. The first octets identify the network, and the later ones identify the specific device. Think of it like a phone number: area code + local number.
Your device settings show your private IP (e.g. 192.168.x.x), which is used only within your local network. This page shows your public IP, assigned by your ISP and visible to the outside world. Your router translates between the two using NAT (Network Address Translation).
