What is an IP address?
An IP address (Internet Protocol address) is a unique identifier assigned to a device
connected to the Internet. It enables communication between your computer, smartphone,
or router and remote servers.
In practice, an IP address works much like a postal address – it tells servers
where data should be delivered and where incoming requests originate from.
What is an IP address used for?
An IP address is used for, among other things:
- establishing connections with web servers,
- identifying the source of network traffic,
- diagnosing Internet connection issues,
- access control (for example, IP whitelisting in admin panels),
- determining the approximate location of a user.
Static vs dynamic IP address – what is the difference?
In most residential Internet connections, users are assigned a
dynamic IP address, which may change after reconnecting
to the network or after a certain period of time.
A static IP address remains unchanged and is commonly used
by businesses, servers, and monitoring systems where consistent and predictable
access from a single address is required.
IPv4 vs IPv6 – what is the difference?
Currently, two versions of the Internet Protocol are in use:
IPv4 and IPv6.
IPv4 is the older and still most widely used standard, where an IP address
is written as four numbers separated by dots (for example, 192.168.1.1).
Due to the limited number of available IPv4 addresses, the newer
IPv6 protocol was introduced. IPv6 addresses are much longer,
written in hexadecimal format and separated by colons (for example,
2001:0db8:85a3:0000:0000:8a2e:0370:7334), allowing for a virtually
unlimited number of unique addresses.
In practice, many users use both protocols simultaneously. This depends on
the configuration of the Internet service provider, the router, and whether
a given website or service supports IPv6. The tool above can display both
IPv4 and IPv6 addresses if they are available for your connection.
When is it useful to know your IP address?
Knowing your IP address can be helpful in situations such as:
- configuring access to admin panels or servers,
- reporting technical issues to an Internet service provider or administrator,
- setting up firewalls, VPNs, or security rules,
- verifying whether traffic is routed through a VPN or proxy server,
- analyzing server logs and network traffic.
How can I check my IP address?
The easiest way to check your public IP address is to use the tool available above.
It requires no configuration and no additional software installation.
Alternatively, you can find your IP address in your router settings, operating system
network configuration, or by using command-line tools. However, the online method
is the fastest and most convenient.
